Google Colab GPU not working

@mgreenbe FWIW, I’m having this problem too:

  1. 01_intro.ipynb takes easily over an hour at the cell that runs
learn = cnn_learner(dls, resnet34, metrics=error_rate)
learn.fine_tune(1)
  1. torch.cuda.is_available() returns True

  2. !pip show fastai shows fastai is version 2.2.5
