Installation

First, you might need uninstall existed packages like

pip uninstall onnxruntime onnxruntime-gpu -y

Then choose only one of the following based on cuda version (or CPU only) to install:

CUDA 13.x

pip install flatbuffers numpy packaging protobuf sympy
pip install --pre --index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/ort-cuda-13-nightly/pypi/simple/ onnxruntime-gpu

CUDA 12.x

pip install flatbuffers numpy packaging protobuf sympy
pip install --pre --index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/ORT-Nightly/pypi/simple/ onnxruntime-gpu

CPU Only

pip install flatbuffers numpy packaging protobuf sympy
pip install --pre --index-url https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/ORT-Nightly/pypi/simple/ onnxruntime
