Why GPU is not working in Windows 10

Hello guys,

I bought new laptop which contain geforce rtx 2060 and first i wanted to use it in basic mnist set. I installed conda and fast ai and all dependicies but when i just try to run this notebook, it took 1 min to finish one epoch.

When i check the gpu( torch.cuda.get_device_name(0) ) i got ‘GeForce RTX 2060’ output. But why one epoch takes 1 min while in the original notebook it took just 6 second?

By the way, I also did the things that mentioned by @chiz in here but still it is the same.

I have the same issue (GTX 1080). Did you ever get a solution to this issue?
