Thanks for the reply!
Since my GPU is only compatible with CUDA 10.1, I think I am restricted to Pytorch v1.7.0 according to this table: pytorch/CONTRIBUTING.md at master · pytorch/pytorch · GitHub
I did not fully understand, how exactly CUDA and Pytorch versions depend on each other, so if you think that a newer version might also work, please let me know.
Unfortunately, I was not able to find the older issue (were the square brackets supposed to be a link?).
I found a bunch of other link errors, but none of them seemed to fit my problem.
Could you maybe provide a link to the issue you meant?
