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 #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.

[kminhta]

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/

[yinghu5]

Dear all,

I saw several similar issues during Windows installation in IPEX Git Hub. Like:
#485
#429 [Import intel_extension_for_pytorch fails on windows11

As we analyzed, the main root cause may still be in the installation environment, please note:

Neither “windows powershell” or “anaconda powershell prompt” does not work, if using conda prompt, we need to use "anaconda prompt".
please use the anaconda prompt itself, not in PS (powershell) environment. #485

Install step missing like missing install oneAPI or missing activate oneAPI, or missing other package:
conda install pkg-config libuv etc.

Other dependencies missing, like MSVC redistribution files.
so in summary, please create a new conda environment and
follow the install guide: https://intel.github.io/intel-extension-for-pytorch/index.html#installation?platform=gpu&version=v2.1.30%2bxpu&os=windows&package=pip

Pre-requisites installation in order :
3.1) GPU driver
3.2) MSVC environment or Install Microsoft Visual C++ Redistributable
Install Microsoft Visual C++ Redistributable from Microsoft website.
3.3) Install oneAPI: 2024.1 {as no download link is available for 2023.2 anymore}
(https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html)
3.4) open Python environment, like miconda3(latest) Python: 3.10

In anaconda prompt (please notes some VS code, call power shell by default)

3.5) Steps to reproduce:
conda create --name llmenv python=3.10
conda activate llm
call "C:\Program Files (x86)\Intel\oneAPI\compiler\latest\env\vars.bat" -> DPCPPROOT
call "C:\Program Files (x86)\Intel\oneAPI\compiler\mkl\env\vars.bat" -> MKLROOT

conda install pkg-config libuv
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/
Sanity test:
python -c "import torch; import intel_extension_for_pytorch as ipex; print(torch.version); print(ipex.version); [print(f'[{i}]: {torch.xpu.get_device_properties(i)}') for i in range(torch.xpu.device_count())];"

If you followed those and still run into the problem, please let us know the installation steps you are using. and collect your envs by this collect_env.py

Thanks
