Build Instructions

{: .no_toc }

To build ORT with training support add --enable_training build instruction.

All other build options are the same for inferencing as they are for training.

Windows

.\build.bat --config RelWithDebInfo --build_shared_lib --parallel --enable_training

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/macOS

./build.sh --config RelWithDebInfo --build_shared_lib --parallel --enable_training

GPU / CUDA

Prerequisites

{: .no_toc }

The default NVIDIA GPU build requires CUDA runtime libraries installed on the system:

• CUDA 10.2
• cuDNN 8.0
• NCCL 2.7
• OpenMPI 4.0.4
  • See install_openmpi.sh

These dependency versions should reflect what is in Dockerfile.training.

Build instructions

{: .no_toc }

1. Checkout this code repo with git clone https://github.com/microsoft/onnxruntime

2. Set the environment variables: adjust the path for location your build machine

   export CUDA_HOME=<location for CUDA libs> # e.g. /usr/local/cuda
   export CUDNN_HOME=<location for cuDNN libs> # e.g. /usr/local/cuda
   export CUDACXX=<location for NVCC> #e.g. /usr/local/cuda/bin/nvcc
   export PATH=<location for openmpi/bin/>:$PATH
   export LD_LIBRARY_PATH=<location for openmpi/lib/>:$LD_LIBRARY_PATH
   export MPI_CXX_INCLUDE_PATH=<location for openmpi/include/>
   

3. Create the ONNX Runtime wheel

   • Change to the ONNX Runtime repo base folder: cd onnxruntime
   • Run ./build.sh --enable_training --use_cuda --config=RelWithDebInfo --build_wheel

   This produces the .whl file in ./build/Linux/RelWithDebInfo/dist for ONNX Runtime Training.

GPU / ROCM

Prerequisites

{: .no_toc }

The default AMD GPU build requires ROCM software toolkit installed on the system:

• ROCM
• OpenMPI 4.0.4
  • See install_openmpi.sh

These dependency versions should reflect what is in Dockerfile.training.

Build instructions

{: .no_toc }

1. Checkout this code repo with git clone https://github.com/microsoft/onnxruntime

2. Create the ONNX Runtime wheel

   • Change to the ONNX Runtime repo base folder: cd onnxruntime
   • Run ./build.sh --config RelWithDebInfo --enable_training --build_wheel --use_rocm --rocm_home /opt/rocm --nccl_home /opt/rocm --mpi_home <location for openmpi>

   This produces the .whl file in ./build/Linux/RelWithDebInfo/dist for ONNX Runtime Training.

DNNL and MKLML

Build Instructions

{: .no_toc }

Linux

./build.sh --enable_training --use_dnnl

Windows

.\build.bat --enable_training --use_dnnl

Add --build_wheel to build the ONNX Runtime wheel

This will produce a .whl file in build/Linux/RelWithDebInfo/dist for ONNX Runtime Training
