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 according to the version compatibility matrix.
- The path to the CUDA installation must be provided via the CUDA_PATH environment variable, or the --cuda_home parameter.
- The path to the cuDNN installation (include the cuda folder in the path) must be provided via the cuDNN_PATH environment variable, or --cudnn_home parameter. The cuDNN path should contain bin, include and lib directories.
- 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.

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

Install CUDA and cuDNN
- The TensorRT execution provider for ONNX Runtime is built and tested up to CUDA 11.8 and cuDNN 8.9.
- The path to the CUDA installation must be provided via the CUDA_PATH environment variable, or the --cuda_home parameter. The CUDA path should contain bin, include and lib 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 (path to cudnn bin/include/lib) must be provided via the cuDNN_PATH environment variable, or --cudnn_home parameter.
  - On Windows, cuDNN requires zlibwapi.dll. Feel free to place this dll under path_to_cudnn/bin
Install TensorRT
- The TensorRT execution provider for ONNX Runtime is built and tested up to TensorRT 8.6.
- The path to TensorRT installation must be provided via the --tensorrt_home parameter.
- By default, ONNX Runtime uses TensorRT built-in parser library, instead of generating the parser library from open-sourced onnx-tensorrt submodule.
  - To update TensorRT parser version, simply linking path to new TensorRT folder when building Onnx Runtime.
  - To generate open-sourced parser when building ONNX Runtime, add additional --use_tensorrt_oss_parser parameter next to the parameter --use_tensorrt in build commands below.
    - The default version of open-sourced onnx-tensorrt parser is encoded in cmake/deps.txt.
    - To specify a different version, please update the commit link for the onnx-tensorrt repository, and run sha1sum command on the onnx-tensorrt zip file to acquire the SHA1 hash

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.

Create a minimal build with XNNPACK EP support

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

<ONNX Runtime repository root>./build.sh --config <Release|Debug|RelWithDebInfo|MinSizeRel> --use_xcode \
           --ios --ios_sysroot iphoneos --osx_arch arm64 --apple_deploy_target <minimal iOS version> --use_xnnpack --minimal_build extended --disable_ml_ops --disable_exceptions --build_shared_lib --skip_tests --include_ops_by_config <config file from model conversion>

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

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

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

Build Instructions

Linux

./build.sh --config <Release|Debug|RelWithDebInfo> --build_shared_lib --parallel --use_cann

Notes

The CANN execution provider supports building for both x64 and aarch64 architectures.
CANN excution provider now is only supported on Linux.

Azure

See the Azure Execution Provider documentation for more details.

Prerequisites

For Linux, before building, please:

install openssl dev package into the system, which is openssl-dev for redhat and libssl-dev for ubuntu.
if have multiple openssl dev versions installed in the system, please set environment variable “OPENSSL_ROOT_DIR” to the desired version, for example:

set OPENSSL_ROOT_DIR=/usr/local/ssl3.x/

Build Instructions

Windows

build.bat --config <Release|Debug|RelWithDebInfo> --build_shared_lib --build_wheel --use_azure

Linux

./build.sh --config <Release|Debug|RelWithDebInfo> --build_shared_lib --build_wheel --use_azure
