RuntimeError: expected device cuda:0 but got device cpu in audio.ipynb
In https://github.com/fastai/course-v3/blob/master/nbs/dl2/audio.ipynb
This error occurs at show_spectro(ll.train[4][0])
If ll is on CPU instead of a CUDA device it works fine. Is it expected to run on CUDA device or is it fine to run it on CPU?
