OSError: [WinError 127] The specified procedure could not be found

Question

While importing torch (import torch) I'm facing the following error message: OSError: [WinError 127] The specified procedure could not be found. Error loading "C:\Users\myUserName\anaconda3\lib\site-packages\torch\lib\jitbackend_test.dll" or one of its dependencies.

I tried the suggestion from this article but without success.

Any ideas how to fix it?

My environment:

• NVIDIA GeForce GTX 1650
• Windows 11
• Cuda 11.5
• Conda 4.10.3
• Python 3.8.5
• Torch 1.10
• Microsoft Visual C++ Redistributable installed (https://aka.ms/vs/17/release/vc_redist.x64.exe)

I very, very, very much doubt that CUDA 11.5 will be the right version for whatever build of Pytorch you have, but that might not be your only problem – Nehemiah

Answer 1

Fortunately, after extensive research, I found a solution. Someone suggested me to create a new conda environment. And that worked for me!

Solution:

1. create new conda env by: conda create --name new-env
2. install python: conda install python=3.8.5
3. run: conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
4. test cuda: import torch; print(torch.version.cuda); print(torch.cuda.is_available())

Answer 2

reinstalling problematic library (torchaudio) + closing and reopening terminal fixed the issue for me ( on windows )

python -m pip install --upgrade torchaudio
