widgets.FileUpload() Error

Just got started with the FastAI course and loving it so far! However, I’m facing an issue while trying to upload an image to 01_intro.ipynb, as shown in the screenshot attached. Here’s the complete error -

Note: Using a local instance of JupyterLab

I’m on a mac, and I had this too, I googled around a bit and pip install -U ipywidgets did it for me. I’m not using venv or anything like that. Total python novice, doing it all quick’n’dirty.

If that works you might get caught out on the creation of the image from the upload a few cells down. Looking at the 2020 course thread on this issue got me unblocked widgets.FileUpload() not working - #29 by ipetrousov
