Build ONNX Runtime with Execution Providers

Contents

Execution Provider Shared Libraries

The oneDNN, TensorRT, OpenVINO™, and CANN providers are built as shared libraries vs being statically linked into the main onnxruntime. This enables them to be loaded only when needed, and if the dependent libraries of the provider are not installed onnxruntime will still run fine, it just will not be able to use that provider. For non shared library providers, all dependencies of the provider must exist to load onnxruntime.

Built files

On Windows, shared provider libraries will be named ‘onnxruntime_providers_*.dll’ (for example onnxruntime_providers_openvino.dll). On Unix, they will be named ‘libonnxruntime_providers_*.so’ On Mac, they will be named ‘libonnxruntime_providers_*.dylib’.

There is also a shared library that shared providers depend on called onnxruntime_providers_shared (with the same naming convension applied as above).

Note: It is not recommended to put these libraries in a system location or added to a library search path (like LD_LIBRARY_PATH on Unix). If multiple versions of onnxruntime are installed on the system this can make them find the wrong libraries and lead to undefined behavior.

Loading the shared providers

Shared provider libraries are loaded by the onnxruntime code (do not load or depend on them in your client code). The API for registering shared or non shared providers is identical, the difference is that shared ones will be loaded at runtime when the provider is added to the session options (through a call like OrtSessionOptionsAppendExecutionProvider_OpenVINO or SessionOptionsAppendExecutionProvider_OpenVINO in the C API). If a shared provider library cannot be loaded (if the file doesn’t exist, or its dependencies don’t exist or not in the path) then an error will be returned.

The onnxruntime code will look for the provider shared libraries in the same location as the onnxruntime shared library is (or the executable statically linked to the static library version).

CUDA

Prerequisites

  • Install CUDA and cuDNN
    • The CUDA execution provider for ONNX Runtime is built and tested with CUDA 11.8, 12.2 and cuDNN 8.9. Check here for more version information.
    • The path to the CUDA installation must be provided via the CUDA_HOME environment variable, or the --cuda_home parameter. The installation directory should contain bin, include and lib sub-directories.
    • The path to the CUDA bin directory must be added to the PATH environment variable so that nvcc is found.
    • The path to the cuDNN installation must be provided via the CUDNN_HOME environment variable, or --cudnn_home parameter. In Windows, the installation directory should contain bin, include and lib sub-directories.
    • cuDNN 8.* requires ZLib. Follow the cuDNN 8.9 installation guide to install zlib in Linux or Windows.
    • In Windows, the path to the cuDNN bin directory must be added to the PATH environment variable so that cudnn64_8.dll is found.

Build Instructions

Windows 

.\build.bat --use_cuda --cudnn_home <cudnn home path> --cuda_home <cuda home path>

Linux 

./build.sh --use_cuda --cudnn_home <cudnn home path> --cuda_home <cuda home path>

A Dockerfile is available here.

Build Options

To specify GPU architectures (see Compute Capability), you can append parameters like --cmake_extra_defines CMAKE_CUDA_ARCHITECTURES=80;86;89.

With --cmake_extra_defines onnxruntime_USE_CUDA_NHWC_OPS=ON, the CUDA EP can be compiled with additional NHWC ops. This option is not enabled by default due to the small amount of supported NHWC operators.

Another very helpful CMake build option is to build with NVTX support (--cmake_extra_defines onnxruntime_ENABLE_NVTX_PROFILE=ON) that will enable much easier profiling using Nsight Systems and correlates CUDA kernels with their actual ONNX operator.

--enable_cuda_line_info or --cmake_extra_defines onnxruntime_ENABLE_CUDA_LINE_NUMBER_INFO=ON will enable NVCC generation of line-number information for device code. It might be helpful when you run Compute Sanitizer tools on CUDA kernels.

If your Windows machine has multiple versions of CUDA installed and you want to use an older version of CUDA, you need append parameters like --cuda_version <cuda version>.

When your build machine has many CPU cores and less than 64 GB memory, there is chance of out of memory error like nvcc error : 'cicc' died due to signal 9. The solution is to limit number of parallel NVCC threads with parameters like --parallel 4 --nvcc_threads 1.

Notes on older versions of ONNX Runtime, CUDA and Visual Studio

  • Depending on compatibility between the CUDA, cuDNN, and Visual Studio versions you are using, you may need to explicitly install an earlier version of the MSVC toolset.
  • For older version of ONNX Runtime and CUDA, and Visual Studio:
    • CUDA 10.0 is known to work with toolsets from 14.11 up to 14.16 (Visual Studio 2017 15.9), and should continue to work with future Visual Studio versions
    • CUDA 9.2 is known to work with the 14.11 MSVC toolset (Visual Studio 15.3 and 15.4)
      • To install the 14.11 MSVC toolset, see this page.
      • To use the 14.11 toolset with a later version of Visual Studio 2017 you have two options:

        1. Setup the Visual Studio environment variables to point to the 14.11 toolset by running vcvarsall.bat, prior to running the build script. e.g. if you have VS2017 Enterprise, an x64 build would use the following command "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" amd64 -vcvars_ver=14.11 For convenience, .\build.amd64.1411.bat will do this and can be used in the same way as .\build.bat. e.g. ` .\build.amd64.1411.bat –use_cuda`

        2. Alternatively, if you have CMake 3.13 or later you can specify the toolset version via the --msvc_toolset build script parameter. e.g. .\build.bat --msvc_toolset 14.11

  • If you have multiple versions of CUDA installed on a Windows machine and are building with Visual Studio, CMake will use the build files for the highest version of CUDA it finds in the BuildCustomization folder. e.g. C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\VC\VCTargets\BuildCustomizations. If you want to build with an earlier version, you must temporarily remove the ‘CUDA x.y.*’ files for later versions from this directory.

TensorRT

See more information on the TensorRT Execution Provider here.

Prerequisites

  • Follow instructions for CUDA execution provider to install CUDA and cuDNN, and setup environment variables.
  • Follow instructions for installing TensorRT
    • The TensorRT execution provider for ONNX Runtime is built and tested with TensorRT 8.6.
    • The path to TensorRT installation must be provided via the --tensorrt_home parameter.
    • ONNX Runtime uses TensorRT built-in parser from tensorrt_home by default.
    • To use open-sourced onnx-tensorrt parser instead, add --use_tensorrt_oss_parser parameter in build commands below.
      • The default version of open-sourced onnx-tensorrt parser is encoded in cmake/deps.txt.
      • To specify a different version of onnx-tensorrt parser:
        • Select the commit of onnx-tensorrt that you preferred;
        • Run sha1sum command with downloaded onnx-tensorrt zip file to acquire the SHA1 hash
        • Update cmake/deps.txt with updated onnx-tensorrt commit and hash info.

Dockerfile instructions are available here

NVIDIA Jetson TX1/TX2/Nano/Xavier

Build Instructions

These instructions are for the latest JetPack SDK 6.0 for Jetson Orin.

  1. Clone the ONNX Runtime repo on the Jetson host

    git clone --recursive https://github.com/microsoft/onnxruntime

  2. Specify the CUDA compiler, or add its location to the PATH.

    1. Starting with CUDA 11.8, Jetson users on JetPack 5.0+ can upgrade to the latest CUDA release without updating the JetPack version or Jetson Linux BSP (Board Support Package). CUDA version 11.8 with JetPack 5.1.2 has been tested on Jetson when building ONNX Runtime 1.16.

      1. Check this official blog for CUDA upgrade instruction.

      2. CUDA 12.x is only available to Jetson Orin and newer series (CUDA compute capability >= 8.7). Check here for compute capability datasheet. JetPack 6.0 comes preinstalled with CUDA 12.2

    2. CMake can’t automatically find the correct nvcc if it’s not in the PATH. nvcc can be added to PATH via:

      export PATH="/usr/local/cuda/bin:${PATH}"

      or:

      export CUDACXX="/usr/local/cuda/bin/nvcc"

  3. Install the ONNX Runtime build dependencies on the Jetpack host:

    sudo apt install -y --no-install-recommends \
  build-essential software-properties-common libopenblas-dev \
  libpython3.8-dev python3-pip python3-dev python3-setuptools python3-wheel

  4. Cmake is needed to build ONNX Runtime. The minimum required CMake version is 3.26 (version 3.27.4 has been tested). This can be either installed by:

    1. (Unix/Linux) Build from source. Download sources from https://cmake.org/download/ and follow https://cmake.org/install/ to build from source.
    2. (Ubuntu) Install deb package via apt repository: e.g https://apt.kitware.com/

  5. Build the ONNX Runtime Python wheel (update path to CUDA/CUDNN/TensorRT libraries if necessary):

    1. Build onnxruntime-gpu wheel with CUDA and TensorRT support:

      ./build.sh --config Release --update --build --parallel --build_wheel \
--use_tensorrt --cuda_home /usr/local/cuda --cudnn_home /usr/lib/aarch64-linux-gnu \
--tensorrt_home /usr/lib/aarch64-linux-gnu

​ Notes:

  • By default, onnxruntime-gpu wheel file will be captured under path_to/onnxruntime/build/Linux/Release/dist/ (build path can be customized by adding --build_dir followed by a customized path to the build command above).

  • For a portion of Jetson devices like the Xavier series, higher power mode involves more cores (up to 6) to compute but it consumes more resource when building ONNX Runtime. Set --parallel 2 or smaller in the build command if system is hanging and OOM happens.

    oneDNN

NNAPI

Usage of NNAPI on Android platforms is via the NNAPI Execution Provider (EP).

See the NNAPI Execution Provider documentation for more details.

The pre-built ONNX Runtime Mobile package for Android includes the NNAPI EP.

If performing a custom build of ONNX Runtime, support for the NNAPI EP or CoreML EP must be enabled when building.

Create a minimal build with NNAPI EP support

Please see the instructions for setting up the Android environment required to build. The Android build can be cross-compiled on Windows or Linux.

Once you have all the necessary components setup, follow the instructions to create the custom build, with the following changes:

  • Replace --minimal_build with --minimal_build extended to enable support for execution providers that dynamically create kernels at runtime, which is required by the NNAPI EP.
  • Add --use_nnapi to include the NNAPI EP in the build

Example build commands with the NNAPI EP enabled

Windows example:

<ONNX Runtime repository root>.\build.bat --config MinSizeRel --android --android_sdk_path D:\Android --android_ndk_path D:\Android\ndk\21.1.6352462\ --android_abi arm64-v8a --android_api 29 --cmake_generator Ninja --minimal_build extended --use_nnapi --disable_ml_ops --disable_exceptions --build_shared_lib --skip_tests --include_ops_by_config <config file from model conversion>

Please see the instructions for setting up the iOS environment required to build. The iOS/macOS build must be performed on a mac machine.

Once you have all the necessary components setup, follow the instructions to create the custom build, with the following changes:

  • Replace --minimal_build with --minimal_build extended to enable support for execution providers that dynamically create kernels at runtime, which is required by the CoreML EP.
  • Add --use_coreml to include the CoreML EP in the build

XNNPACK

Usage of XNNPACK on Android/iOS/Windows/Linux platforms is via the XNNPACK EP.

See the XNNPACK Execution Provider documentation for more details.

The pre-built ONNX Runtime package(onnxruntime-android) for Android includes the XNNPACK EP.

The pre-built ONNX Runtime Mobile package for iOS, onnxruntime-c and onnxruntime-objc in CocoaPods, includes the XNNPACK EP. (Package onnxruntime-objc with XNNPACK will be available since 1.14.)

If performing a custom build of ONNX Runtime, support for the XNNPACK EP must be enabled when building.

Build for Android

Create a minimal build with XNNPACK EP support

Please see the instructions for setting up the Android environment required to build. The Android build can be cross-compiled on Windows or Linux.

Once you have all the necessary components setup, follow the instructions to create the custom build, with the following changes:

  • Replace --minimal_build with --minimal_build extended to enable support for execution providers that dynamically create kernels at runtime, which is required by the XNNPACK EP.
  • Add --use_xnnpack to include the XNNPACK EP in the build
Example build commands with the XNNPACK EP enabled

Windows example:

<ONNX Runtime repository root>.\build.bat --config MinSizeRel --android --android_sdk_path D:\Android --android_ndk_path D:\Android\ndk\21.1.6352462\ --android_abi arm64-v8a --android_api 29 --cmake_generator Ninja --minimal_build extended --use_xnnpack --disable_ml_ops --disable_exceptions --build_shared_lib --skip_tests --include_ops_by_config <config file from model conversion>

Linux example:

<ONNX Runtime repository root>./build.sh --config MinSizeRel --android --android_sdk_path /Android --android_ndk_path /Android/ndk/21.1.6352462/ --android_abi arm64-v8a --android_api 29 --minimal_build extended --use_xnnpack --disable_ml_ops --disable_exceptions --build_shared_lib --skip_tests --include_ops_by_config <config file from model conversion>`

If you don’t mind MINIMAL build, you can use the following command to build XNNPACK EP for Android: Linux example:

./build.sh --cmake_generator "Ninja" --android  --android_sdk_path /Android --android_ndk_path /Android/ndk/21.1.6352462/ --android_abi arm64-v8a --android_api 29 --use_xnnpack

Build for iOS (available since 1.14)

A Mac machine is required to build package for iOS. Please follow this guide to set up environment firstly.

Build for Windows 

<ONNX Runtime repository root>.\build.bat --config <Release|Debug|RelWithDebInfo> --use_xnnpack

Build for Linux 

<ONNX Runtime repository root>./build.sh --config <Release|Debug|RelWithDebInfo> --use_xnnpack

CANN

See more information on the CANN Execution Provider here.

Prerequisites

  1. Install the CANN Toolkit for the appropriate OS and target hardware by following documentation for detailed instructions, please.

  2. Initialize the CANN environment by running the script as shown below.

    # Default path, change it if needed.
source /usr/local/Ascend/ascend-toolkit/set_env.sh
