Hi eqy, thanx for the answer.
No I made some sudo apt-get purge *nvidia*
and some apt-get remove *nividia*
there doesn’t seem to be any nvidia programs installed anymore.
for your suggestion : yes I used these installer at first (the CUDA 11.1.1).
The problem is that the command line
conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia
re-installed another version of CUDA over my first one (something like CUDA 11.1.75 if I read correctly ).
And it seems that at some point it broke something.
Now I want to uninstall everything, to try again.
until i succeed.
I tried the commands at this page:
https://stackoverflow.com/questions/43664444/how-can-l-uninstall-pytorch 73
And now the uninstall command says PyTorch is uninstalled. But I can still make a import torch in my python3 environment.
And reinstall with the PyTorch command above is very short and doesn’t seem to go through the whole process again.
Anyway thank you for your time, i will try to get it done.
