Building ONNX Runtime
Dockerfiles are available here to help you get started.
Pre-built packages are available at the locations indicated here.
Getting Started: Build the baseline CPU version of ONNX Runtime from source
Pre-Requisites
- Checkout the source tree:
git clone --recursive https://github.com/Microsoft/onnxruntime cd onnxruntime - Install cmake-3.13 or higher from https://cmake.org/download/.
Build Instructions
Windows
Open Developer Command Prompt for Visual Studio version you are going to use. This will properly setup the environment including paths to your compiler, linker, utilities and header files.
.\build.bat --config RelWithDebInfo --build_shared_lib --parallel
The default Windows CMake Generator is Visual Studio 2017, but you can also use the newer Visual Studio 2019 by passing --cmake_generator "Visual Studio 16 2019" to .\build.bat
Linux
./build.sh --config RelWithDebInfo --build_shared_lib --parallel
Notes
- Please note that these instructions build the debug build, which may have performance tradeoffs
- To build the version from each release (which include Windows, Linux, and Mac variants), see these .yml files for reference: CPU, GPU
- The build script runs all unit tests by default (for native builds and skips tests by default for cross-compiled builds).
- If you need to install protobuf 3.6.1 from source code (cmake/external/protobuf), please note:
- CMake flag protobuf_BUILD_SHARED_LIBS must be turned OFF. After the installation, you should have the 'protoc' executable in your PATH. It is recommended to run
ldconfigto make sure protobuf libraries are found. - If you installed your protobuf in a non standard location it would be helpful to set the following env var:
export CMAKE_ARGS="-DONNX_CUSTOM_PROTOC_EXECUTABLE=full path to protoc"so the ONNX build can find it. Also runldconfig <protobuf lib folder path>so the linker can find protobuf libraries.
- CMake flag protobuf_BUILD_SHARED_LIBS must be turned OFF. After the installation, you should have the 'protoc' executable in your PATH. It is recommended to run
- If you'd like to install onnx from source code (cmake/external/onnx), use:
export ONNX_ML=1 python3 setup.py bdist_wheel pip3 install --upgrade dist/*.whl

Execution Providers
CUDA
Pre-Requisites
- Install CUDA and cuDNN
- ONNX Runtime is built and tested with CUDA 10.0 and cuDNN 7.6 using the Visual Studio 2017 14.11 toolset (i.e. Visual Studio 2017 v15.3). CUDA versions from 9.1 up to 10.1, and cuDNN versions from 7.1 up to 7.4 should also work with Visual Studio 2017.
- 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
cudafolder in the path) must be provided via the cuDNN_PATH environment variable, or--cudnn_home parameter. The cuDNN path should containbin,includeandlibdirectories. - The path to the cuDNN bin directory must be added to the PATH environment variable so that cudnn64_7.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
-
Depending on compatibility between the CUDA, cuDNN, and Visual Studio 2017 versions you are using, you may need to explicitly install an earlier version of the MSVC toolset.
-
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:
-
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=14.11For 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 -
Alternatively, if you have CMake 3.13 or later you can specify the toolset version via the
--msvc_toolsetbuild 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.

Pre-Requisites
- Install CUDA and cuDNN

- The path to the CUDA installation must be provided via the CUDA_PATH environment variable, or the
--cuda_home parameter. The CUDA path should containbin,includeandlibdirectories. - The path to the CUDA
bindirectory must be added to the PATH environment variable so thatnvccis found. - The path to the cuDNN installation (path to folder that contains libcudnn.so) must be provided via the cuDNN_PATH environment variable, or
--cudnn_home parameter.
- Install TensorRT
- The TensorRT execution provider for ONNX Runtime is built on TensorRT 7.x and is tested with TensorRT 7.0.0.11.

NUPHAR
See more information on the Nuphar Execution Provider here.
Pre-Requisites
- The Nuphar execution provider for ONNX Runtime is built and tested with LLVM 9.0.0. Because of TVM's requirement when building with LLVM, you need to build LLVM from source. To build the debug flavor of ONNX Runtime, you need the debug build of LLVM.
- Windows (Visual Studio 2017):

Architectures
x86
Build Intsructions
Windows
- add
--x86argument when launching.\build.bat
Linux
- Must be built on a x86 OS
- add --x86 argument to build.sh
ARM
We have experimental support for Linux ARM builds. Windows on ARM is well tested.
Cross compiling for ARM with Docker (Linux/Windows - FASTER, RECOMMENDED)
This method allows you to compile using a desktop or cloud VM. This is much faster than compiling natively and avoids out-of-memory issues that may be encountered when on lower-powered ARM devices. The resulting ONNX Runtime Python wheel (.whl) file is then deployed to an ARM device where it can be invoked in Python 3 scripts.
See the instructions for the the Dockerfile here.
Cross compiling on Linux (without Docker)
-
Get the corresponding toolchain. For example, if your device is Raspberry Pi and the device os is Ubuntu 16.04, you may use gcc-linaro-6.3.1 from https://releases.linaro.org/components/toolchain/binaries
-
Setup env vars
export PATH=/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin:$PATH export CC=arm-linux-gnueabihf-gcc export CXX=arm-linux-gnueabihf-g++ -
Get a pre-compiled protoc:
You may get it from https://github.com/protocolbuffers/protobuf/releases/download/v3.11.2/protoc-3.11.2-linux-x86_64.zip . Please unzip it after downloading.
-
(optional) Setup sysroot for enabling python extension. (TODO: will add details later)
-
Save the following content as tool.cmake
set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) set(CMAKE_CXX_COMPILER arm-linux-gnueabihf-c++) set(CMAKE_C_COMPILER arm-linux-gnueabihf-gcc) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY) -
Append
-DONNX_CUSTOM_PROTOC_EXECUTABLE=/path/to/protoc -DCMAKE_TOOLCHAIN_FILE=path/to/tool.cmaketo your cmake args, run cmake and make to build it.
Native compiling on Linux ARM device (SLOWER)
Docker build runs on a Raspberry Pi 3B with Raspbian Stretch Lite OS (Desktop version will run out memory when linking the .so file) will take 8-9 hours in total.

Using Visual C++ compilers
-
