Max script compile error - assured

Introduction

When using Elasticsearch, in some rare instances you may see an error such as &#;Too many dynamic script compilations within X minutes&#;. Such an error may be caused by a poor script design where parameters are hard-coded. In other cases this may be due to the script cache being too small or the compilation limit being too low. In this article, I will show how to determine if these default limits are too low, and how these limits can be modified.

Warning

In this blog I will show you how to change default settings used for caching scripts Elasticsearch. Changing these to very large values may impact cluster performance and in the worst case could even cause your cluster to crash.

Script caching

Scripts are cached by default so that they only need to be recompiled when updates occur. However, as these scripts are stored in a cache, if the cache gets filled up, then some of the previously compiled scripts will be removed from the cache and would need to be recompiled again if they are needed in the future. For more information, see the documentation on script caching.

Deprecated script settings (Read this if you are running or earlier)

Versions of Elasticsearch and earlier will compile up to 15 inline scripts per minute. These compiled scripts are then stored in the script cache which by default can store up to scripts.

The statistics for the script cache can be viewed with the following command:

GET /_nodes/stats?metric=script&filter_path=nodes.*.script.*

Which should respond with something similar to the following:

{ "nodes" : { "XfXvXJ7xSLynbdZBsFwG3A" : { "script" : { "compilations" : 28, "cache_evictions" : 0, "compilation_limit_triggered" : 0 } }, "pzrnXnehTrKEN0urD7j9eg" : { "script" : { "compilations" : , "cache_evictions" : , "compilation_limit_triggered" : } } etc

The numbers shown are counted since the last restart of each node. If the  and  have large numbers or are constantly increasing, this may indicate that the cache is churning, and may therefore indicate that the cache is too small.

A high value for  may be a side effect of having a cache that is too small, or possibly poor script design where parameters are hard-coded .

The script cache may be configured by setting  in the configuration file as follows.

sprers.eu_size:

And you can dynamically set  as follows:

PUT _cluster/settings { "persistent": { "sprers.eu_compilations_rate": "/5m" } }

However both of these settings are  now deprecated.

Script settings in Elasticsearch and newer

Starting in Elasticsearch , by default scripts are stored depending on the contexts which they execute in. Contexts allow different defaults to be set for different kinds of scripts that Elasticsearch may execute. There are many contexts available, such as &#;watcher_transform&#;, &#;bucket aggregation&#;, &#;aggs_combine&#;, and many others. For those adventurous enough to look in the source code, instantiation of contexts can be seen with this search on GitHub.

Contexts are enabled by default starting in However, if contexts (for some reason) are not currently enabled, they can be enabled with the following command:

PUT _cluster/settings { "persistent": { "sprers.eu_compilations_rate": "use-context" } }

If contexts are used, they can be viewed with the following command:

GET /_nodes/stats?filter_path=nodes.*.script_sprers.euts

This should respond with a list of the contexts that are used for executing scripts, such as the following:

{ "nodes" : { "lqxteGihTpifU5lvV7BEmg" : { "script_cache" : { "contexts" : [ { "context" : "aggregation_selector", "compilations" : 1, "cache_evictions" : 0, "compilation_limit_triggered" : 0 } etc { "context" : "xpack_template", "compilations" : 0, "cache_evictions" : 0, "compilation_limit_triggered" : 0 } etc

If the response above is empty, then &#;use-context&#; may not be enabled, and can be enabled as described above.

As with previous versions of Elasticsearch, if the  and  have large numbers or are constantly increasing, this may indicate that the cache is churning, and may be an indicator that the cache is too small.

For most contexts, you can compile up to 75 scripts per 5 minutes by default. For ingest contexts, the default script compilation rate is unlimited. For most contexts, the default cache size is  For ingest contexts, the default cache size is  These defaults are given in the documentation on how to use scripts.

You can set  in the configuration file. For example, to set the max size for the context, you would add the following to .

sprers.eu_sprers.eu_max_size:

On the other hand, may be set dynamically. For example you can configure the compilations rate for the context as follows:

PUT _cluster/settings { "persistent": { "sprers.eu_sprers.eu_compilations_rate": "/5m" } }

Conclusion

In this blog, I have shown how you can look deeper into Elasticsearch to try to diagnose the potential cause of script compilation errors, and how to modify default settings if necessary.

Pine compilation and execution errors

Pine cannot determine the referencing length of a series. Try using max_bars_back in the study or strategy function¶

The error appears in cases where Pine wrongly autodetects the required maximum length of series used in a script. This happens when a script’s flow of execution does not allow Pine to inspect the use of series in branches of conditional statements (, or ), and Pine cannot automatically detect how far back the series is referenced. Here is an example of a script causing this problem:

//@version=4study("Requires max_bars_back")test=ifbar_index>test:=roc(close,20)plot(test)

In order to help Pine with detection, you should add the parameter to the script’s or function:

//@version=4study("Requires max_bars_back",max_bars_back=20)test=ifbar_index>test:=roc(close,20)plot(test)

You may also resolve the issue by taking the problematic expression out of the conditional branch, in which case the parameter is not required:

//@version=4study("My Script")test=roc20=roc(close,20)ifbar_index>test:=roc20plot(test)

In cases where the problem is caused by a variable rather than a built-in function ( in our example), you may use the Pine v4 function to explicitly define the referencing length for that variable only. This has the advantage of requiring less runtime resources, but entails that you identify the problematic variable, e.g., variable in the following example:

//@version=4study("My Script")f(off)=>t=s=closeifbar_index>t:=s[off]tplot(f())

This situation can be resolved using the function to define the referencing length of variable only, rather than for all the script’s variables:

//@version=4study("My Script")f(off)=>t=s=closemax_bars_back(s,)ifbar_index>t:=s[off]tplot(f())

When using drawings that refer to previous bars through and , the time series received from this bar will be used to position the drawings on the time axis. Therefore, if it is impossible to determine the correct size of the buffer, this error may occur. To avoid this, you need to use . This behavior is described in more detail in the section about drawings.

Wherever scripting is supported in the Elasticsearch APIs, the syntax follows the same pattern; you specify the language of your script, provide the script logic (or source), and add parameters that are passed into the script:

"script": { "lang": "", "source"

TorchScript¶

TorchScript is a way to create serializable and optimizable models from PyTorch code. Any TorchScript program can be saved from a Python process and loaded in a process where there is no Python dependency.

We provide tools to incrementally transition a model from a pure Python program to a TorchScript program that can be run independently from Python, such as in a standalone C++ program. This makes it possible to train models in PyTorch using familiar tools in Python and then export the model via TorchScript to a production environment where Python programs may be disadvantageous for performance and multi-threading reasons.

For a gentle introduction to TorchScript, see the Introduction to TorchScript tutorial.

For an end-to-end example of converting a PyTorch model to TorchScript and running it in C++, see the Loading a PyTorch Model in C++ tutorial.

Creating TorchScript Code¶

This decorator indicates to the compiler that a function or method should be ignored and replaced with the raising of an exception.

This function provides for conatiner type refinement in TorchScript.

This method is a pass-through function that returns value, mostly used to indicate to the TorchScript compiler that the left-hand side expression is a class instance attribute with type of type.

This method is a pass-through function that returns the_value, used to hint TorchScript compiler the type of the_value.

Mixing Tracing and Scripting¶

In many cases either tracing or scripting is an easier approach for converting a model to TorchScript. Tracing and scripting can be composed to suit the particular requirements of a part of a model.

Scripted functions can call traced functions. This is particularly useful when you need to use control-flow around a simple feed-forward model. For instance the beam search of a sequence to sequence model will typically be written in script but can call an encoder module generated using tracing.

Example (calling a traced function in script):

importtorchdeffoo(x,y):return2*x+ytraced_foo=sprers.eu(foo,(sprers.eu(3),sprers.eu(3)))@sprers.eudefbar(x):returntraced_foo(x,x)

Traced functions can call script functions. This is useful when a small part of a model requires some control-flow even though most of the model is just a feed-forward network. Control-flow inside of a script function called by a traced function is preserved correctly.

Example (calling a script function in a traced function):

[email protected](x,y):sprers.eu()>sprers.eu():r=xelse:r=yreturnrdefbar(x,y,z):returnfoo(x,y)+ztraced_bar=sprers.eu(bar,(sprers.eu(3),sprers.eu(3),sprers.eu(3)))

This composition also works for s as well, where it can be used to generate a submodule using tracing that can be called from the methods of a script module.

Example (using a traced module):

importtorchimporttorchvisionclassMyScriptModule(sprers.eu):def__init__(self):super(MyScriptModule,self).__init__()sprers.eu=sprers.euter(sprers.eu([,,]).resize_(1,3,1,1))sprers.eu=sprers.eu(sprers.eu18(),sprers.eu(1,3,,))defforward(self,input):sprers.eu(sprers.eu)my_script_module=sprers.eu(MyScriptModule())

Debugging¶

Disable JIT for Debugging¶

Setting the environment variable will disable all script and tracing annotations. If there is hard-to-debug error in one of your TorchScript models, you can use this flag to force everything to run using native Python. Since TorchScript (scripting and tracing) is disabled with this flag, you can use tools like to debug the model code. For example:

@sprers.eudefscripted_fn(x:sprers.eu):foriinrange(12):x=x+xreturnxdeffn(x):x=sprers.eu(x)importpdb;sprers.eu_trace()returnscripted_fn(x)traced_fn=sprers.eu(fn,(sprers.eu(4,5),))traced_fn(sprers.eu(3,4))

Debugging this script with works except for when we invoke the function. We can globally disable JIT, so that we can call the function as a normal Python function and not compile it. If the above script is called , we can invoke it like so:

$ PYTORCH_JIT=0 python disable_jit_sprers.eu

and we will be able to step into the function as a normal Python function. To disable the TorchScript compiler for a specific function, see .

Inspecting Code¶

TorchScript provides a code pretty-printer for all instances. This pretty-printer gives an interpretation of the script method’s code as valid Python syntax. For example:

@sprers.eudeffoo(len):# type: (int) -> sprers.eurv=sprers.eu(3,4)foriinrange(len):ifi<rv=rvelse:rv=rv+returnrvprint(sprers.eu)

A with a single method will have an attribute , which you can use to inspect the ’s code. If the has more than one method, you will need to access on the method itself and not the module. We can inspect the code of a method named on a by accessing . The example above produces this output:

deffoo(len:int)->Tensor:rv=sprers.eu([3,4],dtype=None,layout=None,device=None,pin_memory=None)rv0=rvforiinrange(len):sprers.eu(i,10):rv1=sprers.eu(rv0,1.,1)else:rv1=sprers.eu(rv0,1.,1)rv0=rv1returnrv0

This is TorchScript’s compilation of the code for the method. You can use this to ensure TorchScript (tracing or scripting) has captured your model code correctly.

Interpreting Graphs¶

TorchScript also has a representation at a lower level than the code pretty- printer, in the form of IR graphs.

TorchScript uses a static single assignment (SSA) intermediate representation (IR) to represent computation. The instructions in this format consist of ATen (the C++ backend of PyTorch) operators and other primitive operators, including control flow operators for loops and conditionals. As an example:

@sprers.eudeffoo(len):# type: (int) -> sprers.eurv=sprers.eu(3,4)foriinrange(len):ifi<rv=rvelse:rv=rv+returnrvprint(sprers.eu)

follows the same rules described in the Inspecting Code section with regard to method lookup.

The example script above produces the graph:

graph(%len.1 : int): %24 : int = prim::Constant[value=1]() %17 : bool = prim::Constant[value=1]() # sprers.eu %12 : bool? = prim::Constant() %10 : Device? = prim::Constant() %6 : int? = prim::Constant() %1 : int = prim::Constant[value=3]() # sprers.eu %2 : int = prim::Constant[value=4]() # sprers.eu %20 : int = prim::Constant[value=10]() # sprers.eu %23 : float = prim::Constant[value=1]() # sprers.eu %4 : int[] = prim::ListConstruct(%1, %2) %rv.1 : Tensor = aten::zeros(%4, %6, %6, %10, %12) # sprers.eu %rv : Tensor = prim::Loop(%len.1, %17, %rv.1) # sprers.eu block0(%i.1 : int, %rv : Tensor): %21 : bool = aten::lt(%i.1, %20) # sprers.eu %rv : Tensor = prim::If(%21) # sprers.eu block0(): %rv.3 : Tensor = aten::sub(%rv, %23, %24) # sprers.eu -> (%rv.3) block1(): %rv.6 : Tensor = aten::add(%rv, %23, %24) # sprers.eu -> (%rv.6) -> (%17, %rv) return (%rv)

Take the instruction for example.

  • means we assign the output to a (unique) value named , that value is of type and that we do not know its concrete shape.

  • is the operator (equivalent to ) and the input list specifies which values in scope should be passed as inputs. The schema for built-in functions like can be found at Builtin Functions.

  • is the location in the original source file that generated this instruction. In this case, it is a file named sprers.eu, on line 9, and at character

Notice that operators can also have associated , namely the and operators. In the graph print-out, these operators are formatted to reflect their equivalent source code forms to facilitate easy debugging.

Graphs can be inspected as shown to confirm that the computation described by a is correct, in both automated and manual fashion, as described below.

Tracer¶

Tracing Edge Cases¶

There are some edge cases that exist where the trace of a given Python function/module will not be representative of the underlying code. These cases can include:

  • Tracing of control flow that is dependent on inputs (e.g. tensor shapes)

  • Tracing of in-place operations of tensor views (e.g. indexing on the left-hand side of an assignment)

Note that these cases may in fact be traceable in the future.

Automatic Trace Checking¶

One way to automatically catch many errors in traces is by using on the API. takes a list of tuples of inputs that will be used to re-trace the computation and verify the results. For example:

defloop_in_traced_fn(x):result=x[0]foriinrange(sprers.eu(0)):result=result*x[i]returnresultinputs=(sprers.eu(3,4,5),)check_inputs=[(sprers.eu(4,5,6),),(sprers.eu(2,3,4),)]traced=sprers.eu(loop_in_traced_fn,inputs,check_inputs=check_inputs)

Gives us the following diagnostic information:

ERROR: Graphs differed across invocations! Graph diff: graph(%x : Tensor) { %1 : int = prim::Constant[value=0]() %2 : int = prim::Constant[value=0]() %result.1 : Tensor = aten::select(%x, %1, %2) %4 : int = prim::Constant[value=0]() %5 : int = prim::Constant[value=0]() %6 : Tensor = aten::select(%x, %4, %5) %result.2 : Tensor = aten::mul(%result.1, %6) %8 : int = prim::Constant[value=0]() %9 : int = prim::Constant[value=1]() %10 : Tensor = aten::select(%x, %8, %9) - %result : Tensor = aten::mul(%result.2, %10) + %result.3 : Tensor = aten::mul(%result.2, %10) ? ++ %12 : int = prim::Constant[value=0]() %13 : int = prim::Constant[value=2]() %14 : Tensor = aten::select(%x, %12, %13) + %result : Tensor = aten::mul(%result.3, %14) + %16 : int = prim::Constant[value=0]() + %17 : int = prim::Constant[value=3]() + %18 : Tensor = aten::select(%x, %16, %17) - %15 : Tensor = aten::mul(%result, %14) ? ^ ^ + %19 : Tensor = aten::mul(%result, %18) ? ^ ^ - return (%15); ? ^ + return (%19); ? ^ }

This message indicates to us that the computation differed between when we first traced it and when we traced it with the . Indeed, the loop within the body of depends on the shape of the input , and thus when we try another with a different shape, the trace differs.

In this case, data-dependent control flow like this can be captured using instead:

deffn(x):result=x[0]foriinrange(sprers.eu(0)):result=result*x[i]returnresultinputs=(sprers.eu(3,4,5),)check_inputs=[(sprers.eu(4,5,6),),(sprers.eu(2,3,4),)]scripted_fn=sprers.eu(fn)print(scripted_sprers.eu)#print(str(scripted_sprers.eu).strip())forinput_tuplein[inputs]+check_inputs:sprers.eu_close(fn(*input_tuple),scripted_fn(*input_tuple))

Which produces:

graph(%x:Tensor){%5:bool=prim::Constant[value=1]()%1:int=prim::Constant[value=0]()%resultTensor=aten::select(%x,%1,%1)%4:int=aten::size(%x,%1)%result:Tensor=prim::Loop(%4,%5,%result.1)block0(%i:int,%7:Tensor){%Tensor=aten::select(%x,%1,%i)%resultTensor=aten::mul(%7,%10)->(%5,%result.2)}return(%result);}

Tracer Warnings¶

The tracer produces warnings for several problematic patterns in traced computation. As an example, take a trace of a function that contains an in-place assignment on a slice (a view) of a Tensor:

deffill_row_zero(x):x[0]=sprers.eu(*sprers.eu[])returnxtraced=sprers.eu(fill_row_zero,(sprers.eu(3,4),))print(sprers.eu)

Produces several warnings and a graph which simply returns the input:

fill_row_sprers.eu TracerWarning: There are 2 live references to the data region being modified when tracing in-place operator copy_ (possibly due to an assignment). This might cause the trace to be incorrect, because all other views that also reference this data will not reflect this change in the trace! On the other hand, if all other views use the same memory chunk, but are disjoint (e.g. are outputs of sprers.eu), this might still be safe. x[0] = sprers.eu(*sprers.eu[]) fill_row_sprers.eu TracerWarning: Output nr 1. of the traced function does not match the corresponding output of the Python function. Detailed error: Not within tolerance rtol=1e atol=1e at input[0, 1] ( vs. ) and 3 other locations (%) traced = sprers.eu(fill_row_zero, (sprers.eu(3, 4),)) graph(%0 : Float(3, 4)) { return (%0); }

We can fix this by modifying the code to not use the in-place update, but rather build up the result tensor out-of-place with :

deffill_row_zero(x):x=sprers.eu((sprers.eu(1,*sprers.eu[]),x[]),dim=0)returnxtraced=sprers.eu(fill_row_zero,(sprers.eu(3,4),))print(sprers.eu)

Frequently Asked Questions¶

Q: I would like to train a model on GPU and do inference on CPU. What are the best practices?

First convert your model from GPU to CPU and then save it, like so:

cpu_model=gpu_sprers.eu()sample_input_cpu=sample_input_sprers.eu()traced_cpu=sprers.eu(cpu_model,sample_input_cpu)sprers.eu(traced_cpu,"sprers.eu")traced_gpu=sprers.eu(gpu_model,sample_input_gpu)sprers.eu(traced_gpu,"sprers.eu")# later, when using the model:ifuse_gpu:model=sprers.eu("sprers.eu")else:model=sprers.eu("sprers.eu")model(input)

This is recommended because the tracer may witness tensor creation on a specific device, so casting an already-loaded model may have unexpected effects. Casting the model before saving it ensures that the tracer has the correct device information.

Q: How do I store attributes on a ?

Say we have a model like:

importtorchclassModel(sprers.eu):def__init__(self):super(Model,self).__init__()self.x=2defforward(self):sprers.eu=sprers.eu(Model())

If is instantiated it will result in a compilation error since the compiler doesn’t know about . There are 4 ways to inform the compiler of attributes on :

1. - Values wrapped in will work as they do on s

2. - Values wrapped in will work as they do on s. This is equivalent to an attribute (see 4) of type .

3. Constants - Annotating a class member as (or adding it to a list called at the class definition level) will mark the contained names as constants. Constants are saved directly in the code of the model. See builtin-constants for details.

4. Attributes - Values that are a supported type can be added as mutable attributes. Most types can be inferred but some may need to be specified, see module attributes for details.

Q: I would like to trace module’s method but I keep getting this error:

This error usually means that the method you are tracing uses a module’s parameters and you are passing the module’s method instead of the module instance (e.g. vs ).

  • Invoking with a module’s method captures module parameters (which may require gradients) as constants.

  • On the other hand, invoking with module’s instance (e.g. ) creates a new module and correctly copies parameters into the new module, so they can accumulate gradients if required.

To trace a specific method on a module, see

Known Issues¶

If you’re using with TorchScript, the inputs of some of the submodules may be falsely inferred to be , even if they’re annotated otherwise. The canonical solution is to subclass and redeclare with the input typed correctly.

Appendix¶

Migrating to PyTorch Recursive Scripting API¶

This section details the changes to TorchScript in PyTorch If you are new to TorchScript you can skip this section. There are two main changes to the TorchScript API with PyTorch

1. will now attempt to recursively compile functions, methods, and classes that it encounters. Once you call , compilation is “opt-out”, rather than “opt-in”.

2. is now the preferred way to create s, instead of inheriting from . These changes combine to provide a simpler, easier-to-use API for converting your s into s, ready to be optimized and executed in a non-Python environment.

The new usage looks like this:

sprers.euonalasFclassModel(sprers.eu):def__init__(self):super(Model,self).__init__()sprers.eu1=sprers.eu2d(1,20,5)sprers.eu2=sprers.eu2d(20,20,5)defforward(self,x):x=sprers.eu(sprers.eu1(x))sprers.eu(sprers.eu2(x))my_model=Model()my_scripted_model=sprers.eu(my_model)
  • The module’s is compiled by default. Methods called from are lazily compiled in the order they are used in .

  • To compile a method other than that is not called from , add .

  • To stop the compiler from compiling a method, add or . leaves the

  • method as a call to python, and replaces it with an exception. cannot be exported; can.

  • Most attribute types can be inferred, so is not necessary. For empty container types, annotate their types using PEP style class annotations.

  • Constants can be marked with a class annotation instead of adding the name of the member to .

  • Python 3 type hints can be used in place of

As a result of these changes, the following items are considered deprecated and should not appear in new code:
  • The decorator

  • Classes that inherit from

  • The wrapper class

  • The array

  • The function

Modules¶

Warning

The annotation’s behavior changes in PyTorch Before PyTorch the @ignore decorator was used to make a function or method callable from code that is exported. To get this functionality back, use . is now equivalent to . See and for details.

When passed to the function, a 's data is copied to a and the TorchScript compiler compiles the module. The module’s is compiled by default. Methods called from are lazily compiled in the order they are used in , as well as any methods.

(fn)[source]¶

This decorator indicates that a method on an is used as an entry point into a and should be compiled.

implicitly is assumed to be an entry point, so it does not need this decorator. Functions and methods called from are compiled as they are seen by the compiler, so they do not need this decorator either.

Example (using on a method):

sprers.euclassMyModule(sprers.eu):defimplicitly_compiled_method(self,x):returnx+99# `forward` is implicitly decorated with `@sprers.eu`,# so adding it here would have no effectdefforward(self,x):[email protected]_forward(self,x):# When the compiler sees this call, it will compile# `implicitly_compiled_method`sprers.euitly_compiled_method(x)defunused_method(self,x):returnx# `m` will contain compiled methods:# `forward`# `another_forward`# `implicitly_compiled_method`# `unused_method` will not be compiled since it was not called from# any compiled methods and wasn't decorated with `@sprers.eu`m=sprers.eu(MyModule())

Functions¶

Functions don’t change much, they can be decorated with or if needed.

# Same behavior as pre-PyTorch @sprers.eudefsome_fn():return2# Marks a function as ignored, if nothing# ever calls it then this has no [email protected]_fn2():return2# As with ignore, if nothing calls it then it has no effect.# If it is called in script it is replaced with an [email protected]_fn3():importpdb;sprers.eu_trace()return4# Doesn't do anything, this function is already# the main entry [email protected]_fn4():return2

TorchScript Classes¶

Warning

TorchScript class support is experimental. Currently it is best suited for simple record-like types (think a with methods attached).

Everything in a user defined TorchScript Class is exported by default, functions can be decorated with if needed.

Attributes¶

The TorchScript compiler needs to know the types of module attributes. Most types can be inferred from the value of the member. Empty lists and dicts cannot have their types inferred and must have their types annotated with PEP style class annotations. If a type cannot be inferred and is not explicitly annotated, it will not be added as an attribute to the resulting

Old API:

fromtypingimportDictimporttorchclassMyModule(sprers.euModule):def__init__(self):super(MyModule,self).__init__()sprers.eu_dict=sprers.euute({},Dict[str,int])sprers.eu_int=sprers.euute(20,int)m=MyModule()

New API:

fromtypingimportDictclassMyModule(sprers.eu):my_dict:Dict[str,int]def__init__(self):super(MyModule,self).__init__()# This type cannot be inferred and must be sprers.eu_dict={}# The attribute type here is inferred to be `int`sprers.eu_int=20defforward(self):passm=sprers.eu(MyModule())

Constants¶

The type constructor can be used to mark members as constant. If members are not marked constant, they will be copied to the resulting as an attribute. Using opens opportunities for optimization if the value is known to be fixed and gives additional type safety.

Old API:

classMyModule(sprers.euModule):__constants__=['my_constant']def__init__(self):super(MyModule,self).__init__()sprers.eu_constant=2defforward(self):passm=MyModule()

Containers are assumed to have type and be non-optional (see Default Types for more information). Previously, was used to tell the TorchScript compiler what the type should be. Python 3 style type hints are now supported.

Fusion Backends¶

There are a couple of fusion backends available to optimize TorchScript execution. The default fuser on CPUs is NNC, which can perform fusions for both CPUs and GPUs. The default fuser on GPUs is NVFuser, which supports a wider range of operators and has demonstrated generated kernels with improved throughput. See the NVFuser documentation for more details on usage and debugging.

MacroScript Compile error when starting max

Hi there.

Here is the deal.
I’ve made a mapping tool which is meant to be run from the Mapping menu of the Edit UVWs dialog. The macroscript is bundled in an .mzp file, along with an sprers.eu script and an sprers.eu file.
sprers.eu first copies the macro to the usermacros folder and then tells max to run sprers.eu
sprers.eu evaluates the macro, so max is aware of its existence, and creates an entry for it in the appropriate menu.
And that’s it.

This was written and tested (very extensively) on max 9 without any error showing up.
I had some people test it on other versions and some of them had one or both of the following problems.

1st problem:
Sometimes the .mzp file needs to be dropped twice in order for the tool to be installed.
This is bugging me but I can live with it.

2nd problem, which worries me a lot more:
After installing the macro and checking that it ran correctly (which it did), some people have an error popping up every time they restart max. It says MAXScript MacroScript Compile -, followed by the path to the macro, followed by ',offset 0; Exception: – Unknown system exception. But still after that, the tool would run just fine. Which makes me wonder. How can max fail to compile the macro but still execute it correctly?
Once the macro is deleted (and the menu entry removed) the error disappears and everything is back to normal.

I’ve been trying to figure this out for more than two weeks now and I must say that I’m at my wits’ end. This is especially difficult to solve since it runs smoothly on my machine.
If some of you could try it and have a look, it would help me a lot.
(you might need to change the extension of the attached file back to .mzp)

Thanks in advance for your time and help.

Pine compilation and execution errors

Pine cannot determine the referencing length of a series. Try using max_bars_back in the study or strategy function¶

The error appears in cases where Pine wrongly autodetects the required maximum length of series used in a script. This happens when a script’s flow of execution does not allow Pine to inspect the use of series in branches of conditional statements (, or ), and Pine cannot automatically detect how far back the series is referenced. Here is an example of a script causing this problem:

//@version=4study("Requires max_bars_back")test=ifbar_index>test:=roc(close,20)plot(test)

In order to help Pine with detection, you should add the parameter to the script’s or function:

//@version=4study("Requires max_bars_back",max_bars_back=20)test=ifbar_index>test:=roc(close,20)plot(test)

You may also resolve the issue by taking the problematic expression out of the conditional branch, in which case the parameter is not required:

//@version=4study("My Script")test=roc20=roc(close,20)ifbar_index>test:=roc20plot(test)

In cases where the problem is caused by a variable rather than a built-in function ( in our example), you may use the Pine v4 function to explicitly max script compile error the referencing length for that variable only, max script compile error. This has the advantage of requiring less runtime resources, but entails that you max script compile error the problematic variable, e.g., variable in the following example:

//@version=4study("My Script")f(off)=>t=s=closeifbar_index>t:=s[off]tplot(f())

This situation can be resolved using the function to define the referencing length of variable only, max script compile error, rather than for all the script’s variables:

//@version=4study("My Script")f(off)=>t=s=closemax_bars_back(s,)ifbar_index>t:=s[off]tplot(f())

When using drawings that refer to previous bars through andthe time series received from this bar will be used to position the drawings on the time axis. Therefore, if it is impossible to determine the correct size of the buffer, this error may occur. To avoid this, you need to use. This max script compile error is described in more detail in the section about drawings.

Compile error in hidden module: <module name>

  • Article
  • 2 minutes to read

A protected module contains a compilation error. Because the error is in a protected module it cannot be displayed.

This error commonly occurs when code is incompatible with the version or architecture of this application (for example, code in a document targets bit Microsoft Office applications but it is attempting to run on bit Office).

This error has the following cause and solution:

Cause of the error:

  • The error is raised when a compilation error exists in the VBA code brother hl 1430 error lights a protected (hidden) module. The specific compilation error is not exposed because the module is protected.

Possible solutions:

  • If you have access to the VBA code in the document or project, unprotect the module, and then run the code again to view the specific error.

  • If you don't have access to the VBA code in the document, then contact the document author to have the code in the hidden module updated.

"id": "", "params": { } }
Specifies the language the script is written in. Defaults to.

The script itself, which you specify as for an inline script or for a stored script. Use the stored script APIs to create and manage stored scripts.
Specifies any named parameters that are passed into the script as variables. Use parameters instead of hard-coded values to decrease compile time.

Write your first scriptedit

Painless is the default scripting language for Elasticsearch. It is secure, performant, and provides a natural syntax for anyone with a little coding experience.

A Painless script is structured as one or more statements and optionally has one or more user-defined functions at the beginning. A script must always have at least one statement.

The Painless execute API provides the ability to test a script with simple user-defined parameters and receive a result. Let&#;s start with a complete script and review its constituent parts.

First, index a document with a single field so that we have some data to work with:

PUT my-index/_doc/1 { "my_field": 5 }

We can then construct a script that operates on that field and run evaluate the script as part of a query. The following query uses the parameter of the search API to retrieve a script valuation. There&#;s a lot happening here, but we&#;ll break it down the components to understand them individually. For now, you only need to understand that this script takes and operates on it.

GET my-index/_search { "script_fields": { "my_doubled_field": { "script": { "source": "doc['my_field'].value * params['multiplier']", "params": { "multiplier": 2 } } } } }

object

source

The is a standard JSON object that defines scripts under most APIs in Elasticsearch. This object requires to define the script itself. The script doesn&#;t specify a language, so it defaults to Painless.

Use parameters in your scriptedit

The first time Elasticsearch sees a new script, it compiles the script and stores the compiled version in a cache. Compilation can be a heavy process. Rather than hard-coding values in your script, pass them as named instead.

For example, in the previous script, we could have just hard coded values and written a script that is seemingly less complex. We could just retrieve the first value for and then multiply it by :

"source": "return doc['my_field'].value * 2"

Though it works, max script compile error, this solution is pretty inflexible. We have to modify the script source to change the multiplier, and Elasticsearch has to recompile the script every time that the multiplier changes.

Instead of hard-coding values, use named to make scripts flexible, and also reduce compilation time when the script runs. You can now make changes to the parameter without Elasticsearch recompiling the script.

"source": "doc['my_field'].value * params['multiplier']", "params": { "multiplier": 2 }

You can compile up to scripts per 5 minutes by default. For ingest contexts, the default script max script compile error rate is unlimited.

sprers.eu_compilations_rate=/10m

If you compile too many unique scripts within a short time, Elasticsearch rejects the new dynamic scripts with a error.

Shorten your scriptedit

Using syntactic abilities that are native to Painless, you can reduce verbosity in your scripts and make them shorter. Here&#;s a simple script that we can make shorter:

GET my-index/_search { "script_fields": { "my_doubled_field": { "script": { "lang": "painless", "source": "doc['my_field'].value * sprers.eu('multiplier');", "params": { "multiplier": 2 } } } } }

Let&#;s look at a shortened version of the script to see what improvements it includes over the previous iteration:

GET my-index/_search { "script_fields": { "my_doubled_field": { "script": { "source": "field('my_field').get(null) * params['multiplier']", "params": { "multiplier": 2 } } } } }

This version of the script removes several components and simplifies the syntax significantly:

  • The declaration. Because Painless is the default language, you don&#;t need to specify the language if you&#;re writing a Painless script.
  • The keyword. Painless automatically uses the final statement in a script (when possible) to produce a return value in a script context that requires one.
  • The method, which is replaced with brackets. Painless uses a shortcut specifically for the type that max script compile error us to use brackets instead of the lengthier method.
  • The semicolon at the end of the statement. Painless does not require semicolons for the final statement of a block. However, it does require them in other cases to remove ambiguity.

Use this abbreviated syntax anywhere that Elasticsearch supports scripts, such as when you&#;re creating runtime fields.

Store and retrieve scriptsedit

You can store and retrieve scripts from the cluster state using the stored script APIs. Stored scripts reduce compilation time and make searches faster.

Unlike regular scripts, stored scripts require that you specify a script language using the parameter.

To create a script, use the create stored script API. For example, the following request creates a stored script named .

POST _scripts/calculate-score { "script": { "lang": "painless", "source": "sprers.eu(_score * 2) + params['my_modifier']" } }

You can retrieve that script by using the get stored script API.

GET _scripts/calculate-score

To use the stored script in a query, include the script in the declaration:

GET my-index/_search { "query": { "script_score": { "query": { "match": { "message": "some message" } }, "script": { "id": "calculate-score", "params": { "my_modifier": 2 } } } } }

To delete a stored script, submit a delete stored script API max script compile error _scripts/calculate-score

Update documents with scriptsedit

You can use the update API to update documents with a specified script. The script can update, delete, or skip modifying the document. The update API also supports passing a partial document, which is merged into the existing document.

First, let&#;s index a simple document:

PUT my-index/_doc/1 { "counter" : 1, "tags" : ["red"] }

To increment the counter, you can submit an update request with the following script:

POST my-index/_update/1 { "script" : { "source": "ctx._sprers.eur += sprers.eu", "lang": "painless", "params" : { "count" : 4 } } }

Similarly, max script compile error can use an update script to add a tag to the list of tags. Because this is just a list, the tag is added even it exists:

POST my-index/_update/1 { "script": { "source": "ctx._sprers.eu(params['tag'])", "lang": "painless", "params": { "tag": "blue" } } }

You can also remove a tag from the list of epson stylus color 670 error. The method of a Java is available in Painless. It takes the index of the element you want to remove. To avoid a possible runtime error, you first need to make sure the tag exists. If the list contains duplicates of the tag, this script just removes one occurrence.

POST my-index/_update/1 { "script": { "source": "if (ctx._sprers.euns(params['tag'])) { ctx._sprers.eu(ctx._sprers.euf(params['tag'])) }", "lang": "painless", max script compile error, "params": { "tag": "blue" } } }

You can also add and remove fields from a document. For example, this script adds the field :

POST my-index/_update/1 { "script" : "ctx._sprers.eu_field = 'value_of_new_field'" }

Conversely, max script compile error, this script removes the field :

POST my-index/_update/1 { "script" : "ctx._sprers.eu('new_field')" }

Instead of updating the document, you can also change the operation that is executed from within the script. For example, this request deletes the document if the field containsmax script compile error. Otherwise it does nothing ():

POST my-index/_update/1 { "script": { "source": "if (ctx._sprers.euns(params['tag'])) { sprers.eu = 'delete' } else { sprers.eu = 'none' }", "lang": "painless", "params": { "tag": "green" } } }

Wherever scripting is supported in the Elasticsearch APIs, the syntax follows the same pattern; you specify the language of your script, provide the script logic (or source), and add parameters that are passed into the script:

"script": { "lang": "", "source"
