[CUDA] Preload dependent DLLs (#23674)

tianleiwu · guschmue · commit d0a3a0cc391f · 2025-03-05T16:36:18.000-08:00
### Description Changes: (1) Pass --cuda_version in packaging pipeline to build wheel command line so that cuda_version can be saved. Note that cuda_version is also required for generating extra_require for #23659. (2) Update steup.py and onnxruntime_validation.py to save cuda version to capi/build_and_package_info.py. (3) Add a helper function to preload dependent DLLs (MSVC, CUDA, CUDNN) in `__init__.py`. First we will try to load DLLs from nvidia site packages, then try load remaining DLLs with default path settings. ``` import onnxruntime onnxruntime.preload_dlls() ``` To show loaded DLLs, set `verbose=True`. It is also possible to disable loading some types of DLLs like: ``` onnxruntime.preload_dlls(cuda=False, cudnn=False, msvc=False, verbose=True) ``` #### PyTorch and onnxruntime in Windows When working with pytorch, onnxruntime will reuse the CUDA and cuDNN DLLs loaded by pytorch as long as CUDA and cuDNN major versions are compatible. Preload DLLs actually might cause issues (see example 2 and 3 below) in Windows. Example 1: onnxruntime and torch can work together easily. ``` >>> import torch >>> import onnxruntime >>> session = onnxruntime.InferenceSession("model.onnx", providers=["CUDAExecutionProvider"]) >>> onnxruntime.preload_dlls(cuda=False, cudnn=False, msvc=False, verbose=True) ----List of loaded DLLs---- D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\curand64_10.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cufft64_11.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_heuristic64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_engines_precompiled64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_ops64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_adv64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cublasLt64_12.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cublas64_12.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\nvrtc64_120_0.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\nvrtc-builtins64_124.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_engines_runtime_compiled64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_cnn64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn_graph64_9.dll D:\anaconda3\envs\py310\Lib\site-packages\numpy.libs\msvcp140-d64049c6e3865410a7dda6a7e9f0c575.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudart64_12.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cudnn64_9.dll D:\anaconda3\envs\py310\msvcp140.dll D:\anaconda3\envs\py310\msvcp140_1.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\cufftw64_11.dll D:\anaconda3\envs\py310\Lib\site-packages\torch\lib\caffe2_nvrtc.dll D:\anaconda3\envs\py310\vcruntime140_1.dll D:\anaconda3\envs\py310\vcruntime140.dll >>> session.get_providers() ['CUDAExecutionProvider', 'CPUExecutionProvider'] ``` Example 2: Use preload_dlls after `import torch` is not necessary.

This change will make it easier to resolve those issues. This is based on Jian's PR #22506 with extra change to load msvc dlls. #23659 can be used to install CUDA/cuDNN dlls to site packages. Example command line after next official release 1.21: ``` pip install onnxruntime-gpu[cuda,cudnn] ``` If user installed pytorch in Linux, those DLLs are usually installed together with torch.
