widgets.FileUpload() not working

Yeah, I’m running into lots of problems in FastAI so far. This is just one of them. The FileUpload() widget isn’t working for me either.

The Upload button shows up. I can click on it. I can browse for a file. I can select a file. The number in the Upload button increments. Then … nothing. It just does nothing. I can check the images directory through the terminal, and my file never gets uploaded. If I click the button again, it just makes me browse for another file and the counter increments. If I hit Shift Enter it just resets the counter. But no matter what I try, it never actually uploads anything.

I’m on Paperspace/Gradient, if that’s relevant.

I also tried
jupyter labextension install @jupyter-widgets/jupyterlab-manager
and
jupyter labextension install @jupyter-widgets/jupyterlab-manager@2.0
to no effect.

I guess I’ll try some other clunky workaround to get a file into that image folder…
