Just for fun, I started taking a free online course called Practical Deep Learning for Coders. Part of the course involves running things via a Jupyter Notebook, so I’ve been using Google Colab product to run the sample code.

After all, it requires GPUs and Linux, and I’m running Windows with no GPU.

Right off the bat, however, I ran into an error when trying to run the example code - “ModuleNotFoundError: No module named ‘fastai.callback.all’; ‘fastai.callback’ is not a package”.

Here’s the full text of the error:

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

And here’s a screenshot of the error:

It turns out I only needed to copy the Jupyter Notebook to my own Google Drive, which I easily did by clicking on the Copy to Drive button at the top of the notebook:

Copy to Drive button.

I had to approve access to my Google Drive (even though they’re both Google products) which, for whatever reason, involved copy-and-pasting an access code.

The reason I needed to copy the Jupyter Notebook to my Google Drive is that the modules it was importing get imported to my Drive - and, I suppose, counts towards my Google Drive quota.
