TensorRT Safety Runtime Command-Line Wrapper: trtexec_safe

Table Of Contents

Description

trtexec_safe is a performance testing tool for TensorRT safety runtime. trtexec_safe can load a serialized engine file and test the performance of running inference with TensorRT safety runtime. trtexec_safe provides many options, like iterations, average runs, streams, for performance timing.

Note: trtexec_safe only provides the functionality of doing inference with a pre-built engine file. The engine should be built with EngineCapability::kSAFETY. trtexec_safe is not safety-certified, therefore, it could produce AUTOSAR violations in the source code.

Building trtexec_safe

Compile the sample by following the build instructions in the TensorRT README. This will build the trtexec_safe binary.

The options that control compiling against safety runtime or standard runtime are summarized in the following table.

Compile Option Default Description
TRT_SAFETY_INFERENCE_ONLY OFF When enabled, build the infer part only, skip compiling the builder part.

Using trtexec_safe

  1. trtexec_safe requires a prebuilt safe TensorRT engine as input. Use trtexec to build a safe TensorRT engine.

    trtexec --safe --saveEngine=/path/to/safe/engine --model=/path/to/model
    

    where --safe indicates trtexec to build a safety certified TensorRT engine and --saveEngine specifies the path to save the output engine. For other details of trtexec, see <TensorRT root directory>/samples/trtexec/README.md.

  2. Use trtexec_safe to load the engine and run performance testing.

    trtexec_safe --loadEngine=/path/to/safe/engine
    

    trtexec_safe will do inference for several iterations and give a final median execution time on both the CPU and GPU. For other options, refer to the Tool command line arguments section.
