clone()

IPluginV2DynamicExt * bert::EmbLayerNormVarSeqlenPlugin::clone ( ) const

overridevirtual

Clone the plugin object.

This copies over internal plugin parameters as well and returns a new plugin object with these parameters. If the source plugin is pre-configured with configurePlugin(), the returned object should also be pre-configured. The returned object should allow attachToContext() with a new execution context. Cloned plugin objects can share the same per-engine immutable resource (e.g. weights) with the source object (e.g. via ref-counting) to avoid duplication.

getOutputDimensions() [2/3]

virtual DimsExprs nvinfer1::IPluginV2DynamicExt::getOutputDimensions ( int32_t  outputIndex, const DimsExprs *  inputs, int32_t  nbInputs, IExprBuilder &  exprBuilder  )

pure virtualinherited

Get expressions for computing dimensions of an output tensor from dimensions of the input tensors.

Parameters

outputIndex	The index of the output tensor
inputs	Expressions for dimensions of the input tensors
nbInputDims	The number of input tensors
exprBuilder	Object for generating new expressions

This function is called by the implementations of IBuilder during analysis of the network.

Example #1: A plugin has a single output that transposes the last two dimensions of the plugin's single input. The body of the override of getOutputDimensions can be:

DimsExprs output(inputs[0]);
std::swap(output.d[output.nbDims-1], output.d[output.nbDims-2]);
return output;

Example #2: A plugin concatenates its two inputs along the first dimension. The body of the override of getOutputDimensions can be:

DimsExprs output(inputs[0]);
output.d[0] = exprBuilder.operation(DimensionOperation::kSUM, *inputs[0].d[0], *inputs[1].d[0]);
return output;

getOutputDimensions() [3/3]

virtual Dims nvinfer1::IPluginV2::getOutputDimensions ( int32_t  index, const Dims *  inputs, int32_t  nbInputDims  )

pure virtualinherited

Get the dimension of an output tensor.

Parameters

index	The index of the output tensor.
inputs	The input tensors.
nbInputDims	The number of input tensors.

This function is called by the implementations of INetworkDefinition and IBuilder. In particular, it is called prior to any call to initialize().

supportsFormatCombination() [2/2]

virtual bool nvinfer1::IPluginV2DynamicExt::supportsFormatCombination ( int32_t  pos, const PluginTensorDesc *  inOut, int32_t  nbInputs, int32_t  nbOutputs  )

pure virtualinherited

Return true if plugin supports the format and datatype for the input/output indexed by pos.

For this method inputs are numbered 0..(nbInputs-1) and outputs are numbered nbInputs..(nbInputs+nbOutputs-1). Using this numbering, pos is an index into InOut, where 0 <= pos < nbInputs+nbOutputs-1.

TensorRT invokes this method to ask if the input/output indexed by pos supports the format/datatype specified by inOut[pos].format and inOut[pos].type. The override should return true if that format/datatype at inOut[pos] are supported by the plugin. If support is conditional on other input/output formats/datatypes, the plugin can make its result conditional on the formats/datatypes in inOut[0..pos-1], which will be set to values that the plugin supports. The override should not inspect inOut[pos+1..nbInputs+nbOutputs-1], which will have invalid values. In other words, the decision for pos must be based on inOut[0..pos] only.

Some examples:

• A definition for a plugin that supports only FP16 NCHW:

    return inOut.format[pos] == TensorFormat::kLINEAR && inOut.type[pos] == DataType::kHALF;
  

• A definition for a plugin that supports only FP16 NCHW for its two inputs, and FP32 NCHW for its single output:

    return inOut.format[pos] == TensorFormat::kLINEAR && (inOut.type[pos] == pos < 2 ?  DataType::kHALF :
    DataType::kFLOAT);
  

• A definition for a "polymorphic" plugin with two inputs and one output that supports any format or type, but the inputs and output must have the same format and type:

    return pos == 0 || (inOut.format[pos] == inOut.format[0] && inOut.type[pos] == inOut.type[0]);
  

Warning: TensorRT will stop asking for formats once it finds kFORMAT_COMBINATION_LIMIT on combinations.

configurePlugin() [2/3]

virtual void nvinfer1::IPluginV2DynamicExt::configurePlugin ( const DynamicPluginTensorDesc *  in, int32_t  nbInputs, const DynamicPluginTensorDesc *  out, int32_t  nbOutputs  )

pure virtualinherited

Configure the layer.

This function is called by the builder prior to initialize(). It provides an opportunity for the layer to make algorithm choices on the basis of bounds on the input and output tensors, and the target value.

This function is also called once when the resource requirements are changed based on the optimization profiles.

Parameters

in	The input tensors attributes that are used for configuration.
nbInputs	Number of input tensors.
out	The output tensors attributes that are used for configuration.
nbOutputs	Number of output tensors.

configurePlugin() [3/3]

virtual void nvinfer1::IPluginV2Ext::configurePlugin ( const Dims *  inputDims, int32_t  nbInputs, const Dims *  outputDims, int32_t  nbOutputs, const DataType *  inputTypes, const DataType *  outputTypes, const bool *  inputIsBroadcast, const bool *  outputIsBroadcast, PluginFormat  floatFormat, int32_t  maxBatchSize  )

pure virtualinherited

Configure the layer with input and output data types.

This function is called by the builder prior to initialize(). It provides an opportunity for the layer to make algorithm choices on the basis of its weights, dimensions, data types and maximum batch size.

Parameters

inputDims	The input tensor dimensions.
nbInputs	The number of inputs.
outputDims	The output tensor dimensions.
nbOutputs	The number of outputs.
inputTypes	The data types selected for the plugin inputs.
outputTypes	The data types selected for the plugin outputs.
inputIsBroadcast	True for each input that the plugin must broadcast across the batch.
outputIsBroadcast	True for each output that TensorRT will broadcast across the batch.
floatFormat	The format selected for the engine for the floating point inputs/outputs.
maxBatchSize	The maximum batch size.

The dimensions passed here do not include the outermost batch size (i.e. for 2-D image networks, they will be 3-dimensional CHW dimensions). When inputIsBroadcast or outputIsBroadcast is true, the outermost batch size for that input or output should be treated as if it is one. inputIsBroadcast[i] is true only if the input is semantically broadcast across the batch and canBroadcastInputAcrossBatch(i) returned true. outputIsBroadcast[i] is true only if isOutputBroadcastAcrossBatch(i) returned true.

Warning

for the floatFormat field, the values PluginFormat::kCHW4, PluginFormat::kCHW16, and PluginFormat::kCHW32 will not be passed in, this is to keep backward compatibility with TensorRT 5.x series. Use PluginV2IOExt or PluginV2DynamicExt for other PluginFormats.

getWorkspaceSize() [2/3]

virtual size_t nvinfer1::IPluginV2DynamicExt::getWorkspaceSize ( const PluginTensorDesc *  inputs, int32_t  nbInputs, const PluginTensorDesc *  outputs, int32_t  nbOutputs  ) const

pure virtualinherited

Find the workspace size required by the layer.

This function is called after the plugin is configured, and possibly during execution. The result should be a sufficient workspace size to deal with inputs and outputs of the given size or any smaller problem.

Returns

The workspace size.

getWorkspaceSize() [3/3]

virtual size_t nvinfer1::IPluginV2::getWorkspaceSize ( int32_t  maxBatchSize ) const

pure virtualinherited

Find the workspace size required by the layer.

This function is called during engine startup, after initialize(). The workspace size returned should be sufficient for any batch size up to the maximum.

Returns

The workspace size.

enqueue() [2/2]

virtual int32_t nvinfer1::IPluginV2::enqueue ( int32_t  batchSize, const void *const *  inputs, void **  outputs, void *  workspace, cudaStream_t  stream  )

pure virtualinherited

Execute the layer.

Parameters

batchSize	The number of inputs in the batch.
inputs	The memory for the input tensors.
outputs	The memory for the output tensors.
workspace	Workspace for execution.
stream	The stream in which to execute the kernels.

Returns

0 for success, else non-zero (which will cause engine termination).

getTensorRTVersion()

int32_t nvinfer1::IPluginV2DynamicExt::getTensorRTVersion ( ) const

inlineprotectedvirtualinherited

Return the API version with which this plugin was built.

Do not override this method as it is used by the TensorRT library to maintain backwards-compatibility with plugins.

Reimplemented from nvinfer1::IPluginV2.

__attribute__() [1/5]

nvinfer1::IPluginV2DynamicExt::__attribute__ ( (deprecated)  )

protectedinherited

Derived classes should not implement this.

In a C++11 API it would be override final.

Instead, derived classes should override the overload of getOutputDimensions that returns DimsExprs.

Deprecated:

Deprecated interface will be removed in TensorRT 8.0.

__attribute__() [2/5]

nvinfer1::IPluginV2DynamicExt::__attribute__ ( (deprecated)  )

protectedinherited

__attribute__() [4/5]

nvinfer1::IPluginV2DynamicExt::__attribute__ ( (deprecated)  )

protectedinherited

Derived classes should not implement this.

In a C++11 API it would be override final.

This method is not used because it does not allow a plugin to specify mixed formats.

Instead, derived classes should override supportsFormatCombination, which allows plugins to express mixed formats.

Deprecated:

__attribute__() [5/5]

nvinfer1::IPluginV2DynamicExt::__attribute__ ( (deprecated)  ) const

protectedinherited

Derived classes should not implement this.

In a C++11 API it would be override final.

This method is not used because tensors with dynamic shapes do not have an implicit batch dimension, input dimensions might be variable, and outputs might have different floating-point formats.

Instead, derived classes should override the overload of configurePlugin that takes poiners to DynamicPluginTensorDesc.

Deprecated:

Deprecated interface will be removed in TensorRT 8.0.

getOutputDataType() [2/2]

virtual nvinfer1::DataType nvinfer1::IPluginV2Ext::getOutputDataType ( int32_t  index, const nvinfer1::DataType *  inputTypes, int32_t  nbInputs  ) const

pure virtualinherited

Return the DataType of the plugin output at the requested index.

The default behavior should be to return the type of the first input, or DataType::kFLOAT if the layer has no inputs. The returned data type must have a format that is supported by the plugin.

See also

supportsFormat()

Warning

DataType:kBOOL not supported.

isOutputBroadcastAcrossBatch()

virtual bool nvinfer1::IPluginV2Ext::isOutputBroadcastAcrossBatch ( int32_t  outputIndex, const bool *  inputIsBroadcasted, int32_t  nbInputs  ) const

pure virtualinherited

Return true if output tensor is broadcast across a batch.

Parameters

outputIndex	The index of the output
inputIsBroadcasted	The ith element is true if the tensor for the ith input is broadcast across a batch.
nbInputs	The number of inputs

The values in inputIsBroadcasted refer to broadcasting at the semantic level, i.e. are unaffected by whether method canBroadcastInputAcrossBatch requests physical replication of the values.

canBroadcastInputAcrossBatch()

virtual bool nvinfer1::IPluginV2Ext::canBroadcastInputAcrossBatch ( int32_t  inputIndex ) const

pure virtualinherited

Return true if plugin can use input that is broadcast across batch without replication.

Parameters

inputIndex

Index of input that could be broadcast.

For each input whose tensor is semantically broadcast across a batch, TensorRT calls this method before calling configurePlugin. If canBroadcastInputAcrossBatch returns true, TensorRT will not replicate the input tensor; i.e., there will be a single copy that the plugin should share across the batch. If it returns false, TensorRT will replicate the input tensor so that it appears like a non-broadcasted tensor.

This method is called only for inputs that can be broadcast.

attachToContext()

virtual void nvinfer1::IPluginV2Ext::attachToContext ( cudnnContext *  , cublasContext *  , IGpuAllocator *    )

inlinevirtualinherited

Attach the plugin object to an execution context and grant the plugin the access to some context resource.

Parameters

cudnn	The cudnn context handle of the execution context
cublas	The cublas context handle of the execution context
allocator	The allocator used by the execution context

This function is called automatically for each plugin when a new execution context is created. If the plugin needs per-context resource, it can be allocated here. The plugin can also get context-owned CUDNN and CUBLAS context here.

detachFromContext()

virtual void nvinfer1::IPluginV2Ext::detachFromContext ( )

inlinevirtualinherited

Detach the plugin object from its execution context.

This function is called automatically for each plugin when a execution context is destroyed. If the plugin owns per-context resource, it can be released here.

Reimplemented in nvinfer1::plugin::SplitPlugin, nvinfer1::plugin::ProposalPlugin, nvinfer1::plugin::CropAndResizePlugin, nvinfer1::plugin::SpecialSlice, nvinfer1::plugin::ProposalLayer, nvinfer1::plugin::GenerateDetection, nvinfer1::plugin::MultilevelCropAndResize, nvinfer1::plugin::PyramidROIAlign, nvinfer1::plugin::DetectionLayer, nvinfer1::plugin::MultilevelProposeROI, nvinfer1::plugin::Normalize, nvinfer1::plugin::ResizeNearest, nvinfer1::plugin::DetectionOutput, nvinfer1::plugin::RPROIPlugin, nvinfer1::plugin::GroupNormalizationPlugin, nvinfer1::plugin::PriorBox, nvinfer1::plugin::Region, nvinfer1::plugin::InstanceNormalizationPlugin, nvinfer1::plugin::Reorg, nvinfer1::plugin::GridAnchorGenerator, and nvinfer1::plugin::FlattenConcat.

void nvinfer1::IPluginV2Ext::configureWithFormat ( const Dims *  , int32_t  , const Dims *  , int32_t  , DataType  , PluginFormat  , int32_t    )

inlineprotectedvirtualinherited

Derived classes should not implement this.

In a C++11 API it would be override final.

Implements nvinfer1::IPluginV2.

supportsFormat()

virtual bool nvinfer1::IPluginV2::supportsFormat ( DataType  type, PluginFormat  format  ) const

pure virtualinherited

Check format support.

Parameters

type	DataType requested.
format	PluginFormat requested.

Returns

true if the plugin supports the type-format combination.

This function is called by the implementations of INetworkDefinition, IBuilder, and safe::ICudaEngine/ICudaEngine. In particular, it is called when creating an engine and when deserializing an engine.

Warning

for the format field, the values PluginFormat::kCHW4, PluginFormat::kCHW16, and PluginFormat::kCHW32 will not be passed in, this is to keep backward compatibility with TensorRT 5.x series. Use PluginV2IOExt or PluginV2DynamicExt for other PluginFormats.
