Importing spacy pycharm does not fing cudnn_adv_infer64_8.dll

Hi everyone.
i've installed spacy 3.0.5 in a virtual env with python 3.8.6, pytorch 1.7.1, cuda 11.0 and related cudnn but when i try to import spacy occurs that error:

OSError: [WinError 127] Impossibile trovare la procedura specificata. Error loading "C:\Python38_6\lib\site-packages\torch\lib\cudnn_adv_infer64_8.dll" or one of its dependencies.

That dll is in the path described and everything seems to be ok.
Someone can help me?

So to clarify the error, it happens when loading that DLL as part of importing Torch. Since that DLL is in the right location the issue is that something it depends on is in the wrong location. Looking at Torch issues (pytorch/pytorch#37733) it looks like this might be related to having multiple versions of CUDA installed.

I would recommend you uninstall Torch and then reinstall it and make sure it works on its own. You might want to open an issue at the Torch repo too, since this doesn't seem to be spaCy specific.

Thanks for your answer.
I've solved my issue changing the importation order of libraries. Importing spacy as first library solves "magically" the error.
