This weekend I solved this problem by switching my whole system to unstable. I did it because I noticed that your fix for this was already merged into nixpkgs/master. (switching just the nvidia & pytorch modules to unstable didn’t seem to work) It did the trick! Thanks so much!
the only snag was a number of python failures about “ZIP does not support timestamps before 1980”. The fix for that is to unset SOURCE_DATE_EPOCH in the shellHook.
