Issue with Pytorch on windows #12

Closed IlsaCooke closed 4 years ago

IlsaCooke commented 4 years ago

Hey hey,

I am interesting in trying out your new deep learning functionality.

I ran a pull and installed the new version of pyspectools but I am unable to import SpecConstants or MoleculeDetective

This seems to be due to an issue with the install of Pytorch on Windows with Anaconda3. I wasn't able to install the pyspectools update without install Pyspectools myself first via: pip install torch===1.5.0 torchvision===0.6.0 -f https://download.pytorch.org/whl/torch_stable.html

After this the pyspectools install worked fine but if I try to run "import torch" I get the following error:

File "C:\Users\Ilsa Cooke\Documents\Python Scripts\untitled0.py", line 7, in import torch

File "C:\anaconda\lib\site-packages\torch__init__.py", line 81, in ctypes.CDLL(dll)

File "C:\anaconda\lib\ctypes__init.py", line 364, in init__ self._handle = _dlopen(self._name, mode)

OSError: [WinError 126] The specified module could not be found

Any ideas?

Could you try removing torch and torchvision via pip, and reinstall with conda?

So:

pip remove torch torchvision

followed by:

conda install pytorch torchvision cudatoolkit=10.2 -c pytorch

I suspect pip doesn't install/link the required libraries properly, and it's up to conda to do so...

This didn't fix it but from digging around on the Pytorch site I found this solution:

conda install pytorch torchvision cpuonly -c pytorch
