Describe the issue

[WinError 126] The specified module could not be found. Error loading "C:\Users\Admin\pythonProject\lib\site-packages\torch\lib\backend_with_compiler.dll

This is a follow up to https://github.com/intel/intel-extension-for-pytorch/issues/409?

According to this thread https://github.com/pytorch/pytorch/issues/87695#issuecomment-1302036775, it seems like a potential pathing issue. Could you try setting the appropriate equivalent path for your env?

set PATH=%PATH%;C:\Projects\pytorch\Miniconda3\pkgs\intel-openmp-2021.4.0-haa95532_3556\Library\bin (otherwise the import fails with OSError: [WinError 126] The specified module could not be found. Error loading "C:\Projects\pytorch\torch\lib\backend_with_compiler.dll" or one of its dependencies.)

This is a follow up to #409?

According to this thread pytorch/pytorch#87695 (comment), it seems like a potential pathing issue. Could you try setting the appropriate equivalent path for your env?

set PATH=%PATH%;C:\Projects\pytorch\Miniconda3\pkgs\intel-openmp-2021.4.0-haa95532_3556\Library\bin (otherwise the import fails with OSError: [WinError 126] The specified module could not be found. Error loading "C:\Projects\pytorch\torch\lib\backend_with_compiler.dll" or one of its dependencies.)

would you please give me a sample how to set the correct path in the env for this case. It seems there is no intel-openmp installation mentioned in the guideline.

Are you using conda? I think it should just be in your conda path (i.e. ${PATH_TO_CONDA}/pkgs/intel-openmp-{version})

But also, I am unsure if this is the solution. I have not heard from the original reporter and don't have a system readily available to try to reproduce it

@sxunix and all, generally the error caused by environment. Please follow the install step of Intel extension for pytorch, installed oneAPI base toolkits, https://intel.github.io/intel-extension-for-pytorch/index.html#installation?platform=gpu&version=v2.1.30%2bxpu&os=windows&package=pip you don't need install another related library.

please refer #560 , Note: neither “windows powershell” or “anaconda powershell prompt” does not work, if using conda prompt, we need to use "anaconda prompt". open anaconda prompt windows: conda create -n ipex_test python=3.10

conda activate ipex_test

conda install pkg-config libuv # please install it in your conda environment, it is needed. python -m pip install torch==2.1.0.post2 torchvision==0.16.0.post2 torchaudio==2.1.0.post2 intel-extension-for-pytorch==2.1.30 --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
