Thanks again for the help.

I’m not sure why this would be the case.


As far as I understood, CUDA v10.2 and higher require a graphics driver version >= 441.22, as mentioned in the second table here, but the newest version I could find for my GPU is 426 (nvidia offers 425.31 here, but somehow CUDA 10.1 included version 426.00).
Once again, if this has to be seen as a recommendation more than a hard requirement, or if there is another way of getting newer driver versions,  please let me know  .

right link here as well.


I added a third manual fix according to this solution mentioned in your link and will now try again.
Thanks again for your help, I will let you know if it worked.
