TensorRT OSS v8.2.0 EA

TensorRT OSS release corresponding to TensorRT 8.2.0.6 EA release.

Added

• Demo applications showcasing TensorRT inference of HuggingFace Transformers.
  • Support is currently extended to GPT-2 and T5 models.
• Added support for the following ONNX operators:
  • Einsum
  • IsNan
  • GatherND
  • Scatter
  • ScatterElements
  • ScatterND
  • Sign
  • Round
• Added support for building TensorRT Python API on Windows.

Updated

• Notable API updates in TensorRT 8.2.0.6 EA release. See TensorRT Developer Guide for details.
  • Added three new APIs, IExecutionContext: getEnqueueEmitsProfile(), setEnqueueEmitsProfile(), and reportToProfiler() which can be used to collect layer profiling info when the inference is launched as a CUDA graph.
  • Eliminated the global logger; each Runtime, Builder or Refitter now has its own logger.
  • Added new operators: IAssertionLayer, IConditionLayer, IEinsumLayer, IIfConditionalBoundaryLayer, IIfConditionalOutputLayer, IIfConditionalInputLayer, and IScatterLayer.
  • Added new IGatherLayer modes: kELEMENT and kND
  • Added new ISliceLayer modes: kFILL, kCLAMP, and kREFLECT
  • Added new IUnaryLayer operators: kSIGN and kROUND
  • Added new runtime class IEngineInspector that can be used to inspect the detailed information of an engine, including the layer parameters, the chosen tactics, the precision used, etc.
  • ProfilingVerbosity enums have been updated to show their functionality more explicitly.
• Updated TensorRT OSS container defaults to cuda 11.4
• CMake to target C++14 builds.
• Updated following ONNX operators:
  • Gather and GatherElements implementations to natively support negative indices
  • Pad layer to support ND padding, along with edge and reflect padding mode support
  • If layer with general performance improvements.

Removed

• Removed sampleMLP.
• Several flags of trtexec have been deprecated:
  • --explicitBatch flag has been deprecated and has no effect. When the input model is in UFF or in Caffe prototxt format, the implicit batch dimension mode is used automatically; when the input model is in ONNX format, the explicit batch mode is used automatically.
  • --explicitPrecision flag has been deprecated and has no effect. When the input ONNX model contains Quantization/Dequantization nodes, TensorRT automatically uses explicit precision mode.
  • --nvtxMode=[verbose|default|none] has been deprecated in favor of --profilingVerbosity=[detailed|layer_names_only|none] to show its functionality more explicitly.

21.07

Commit used by the 21.07 TensorRT NGC container

Corresponds to the TensorRT-OSS 8.0.1 Release. Details here.

TensorRT OSS v8.0.1

TensorRT OSS release corresponding to TensorRT 8.0.1.6 GA release.

Added

• Added support for the following ONNX operators: Celu, CumSum, EyeLike, GatherElements, GlobalLpPool, GreaterOrEqual, LessOrEqual, LpNormalization, LpPool, ReverseSequence, and SoftmaxCrossEntropyLoss.
• Rehauled Resize ONNX operator, now fully supporting the following modes:
  • Coordinate Transformation modes: half_pixel, pytorch_half_pixel, tf_half_pixel_for_nn, asymmetric, and align_corners.
  • Modes: nearest, linear.
  • Nearest Modes: floor, ceil, round_prefer_floor, round_prefer_ceil.
• Added support for multi-input ONNX ConvTranpose operator.
• Added support for 3D spatial dimensions in ONNX InstanceNormalization.
• Added support for generic 2D padding in ONNX.
• ONNX QuantizeLinear and DequantizeLinear operators leverage IQuantizeLayer and IDequantizeLayer.
  • Added support for tensor scales.
  • Added support for per-axis quantization.
• Added EfficientNMS_TRT, EfficientNMS_ONNX_TRT plugins and experimental support for ONNX NonMaxSuppression operator.
• Added ScatterND plugin.
• Added TensorRT QuickStart Guide.
• Added new samples: engine_refit_onnx_bidaf builds an engine from ONNX BiDAF model and refits engine with new weights, efficientdet and efficientnet samples for demonstrating Object Detection using TensorRT.
• Added support for Ubuntu20.04 and RedHat/CentOS 8.3.
• Added Python 3.9 support.

Changed

• Update Polygraphy to v0.30.3.
• Update ONNX-GraphSurgeon to v0.3.10.
• Update Pytorch Quantization toolkit to v2.1.0.
• Notable TensorRT API updates
  • TensorRT now declares API’s with the noexcept keyword. All TensorRT classes that an application inherits from (such as IPluginV2) must guarantee that methods called by TensorRT do not throw uncaught exceptions, or the behavior is undefined.
  • Destructors for classes with destroy() methods were previously protected. They are now public, enabling use of smart pointers for these classes. The destroy() methods are deprecated.
• Moved RefitMap API from ONNX parser to core TensorRT.
• Various bugfixes for plugins, samples and ONNX parser.
• Port demoBERT to tensorflow2 and update UFF samples to leverage nvidia-tensorflow1 container.

Removed

• IPlugin and IPluginFactory interfaces were deprecated in TensorRT 6.0 and have been removed in TensorRT 8.0. We recommend that you write new plugins or refactor existing ones to target the IPluginV2DynamicExt and IPluginV2IOExt interfaces. For more information, refer to Migrating Plugins From TensorRT 6.x Or 7.x To TensorRT 8.x.x.
  • For plugins based on IPluginV2DynamicExt and IPluginV2IOExt, certain methods with legacy function signatures (derived from IPluginV2 and IPluginV2Ext base classes) which were deprecated and marked for removal in TensorRT 8.0 will no longer be available.
• Removed samplePlugin since it showcased IPluginExt interface, which is no longer supported in TensorRT 8.0.
• Removed sampleMovieLens and sampleMovieLensMPS.
• Removed Dockerfile for Ubuntu 16.04. TensorRT 8.0 debians for Ubuntu 16.04 require python 3.5 while minimum required python version for TensorRT OSS is 3.6.
• Removed support for PowerPC builds, consistent with TensorRT GA releases.

Notes

• We had deprecated the Caffe Parser and UFF Parser in TensorRT 7.0. They are still tested and functional in TensorRT 8.0, however, we plan to remove the support in a future release. Ensure you migrate your workflow to use tf2onnx, keras2onnx or TensorFlow-TensorRT (TF-TRT).
