torch.backends.cudnn.version() returns 7104.
Unfortunately there is no decent command line tool analogous to nvidia-smi for OSX, I’ve used the activity monitor and it does show what appears to be consistent full GPU usage, but it’s a graph only and has no other information so is of limited merit! But it does appear to be in use!
My NVIDIA drivers are also up to date. Maybe it’s just an issue with my GPU not being supported. I will try installing it with NO_CUDA=1 and see if it does the same.
Edit: I installed it with no CUDA and it’s now even slower, it takes 93 seconds versus the 0.6 taken by 0.4.0
I saved the logs from the install: logs here and warnings here
