Cuda.is_available() was returning True - Now False!


Everything has been working fine for a couple of days including torch.cuda.is_available() returning True.

Then at some point this morning, everything suddenly started going slow. I checked torch.cuda.is_available() and it now returns False.

I restarted the kernel, still False. I restarted the Paperspace machine, still False.

I haven’t changed anything but am no longer getting the speed improvements from having the Paperspace GPU.

Any ideas?

Any help gratefully received :slight_smile:

Kind regards,


So I tried using the browser terminal provided by Paperspace to run up Jupyter (I’d been using PuTTY before) and it worked ths time - is_available() returned True and everything was back up and running quickly agan.

No idea why - it shouldn’t make any difference??
