A demo of creating a gradio app with nbdev

app.ipynb

The last step "Convert this notebook into a Gradio app" silently fails, no app.py is created. Tried on VSCode, jupyter, juypter lab, colab and kaggle. When I try the CLI with nbdev_export I get the following error. Is there another way to auto-generate the app.py without manual editing? Thanks.

Tried also installing nbdev with conda or pip, since this PR#1024 seems to be included in release 2.3.9 but still no success. These were in place of first input of the notebook, which installs nbdev 2.3.10. But none of them worked. Also inserted debug=True before name but still silent. What else could I try? Thanks.

Don't use the CLI, use the method I suggested in the blog post 😄 , I'm not certain that the CLI nbdev_export supports this.

Per the blog post, install from github pip install git+https://github.com/fastai/nbdev.git

Thanks, CLI was a fallback, the method in your blog post runs in 0.3 secs, but no app.py in the folder (or nowhere else). Relative or absolute paths like lib_path='/Users/cer/vc/projects/hfds-size/' did not matter. Can't really figure out why it fails. In any case, thanks for the idea and blog post.

from nbdev.export import nb_export
nb_export('app.ipynb', lib_path='.', name='app')

It's hard to debug this way, if you would like to provide a minimally reproducible example it might be easier. The code in a repo format is on HFhub incase that helps. https://huggingface.co/spaces/hamel/hfspace_demo/tree/main

It helped!!! When I downloaded the raw notebook from the gist, somehow the export decorators were damaged under my edits. I think I managed to change one “|” to “!”. My bad. Now I downloaded app.ipynb directly from https://huggingface.co/spaces/hamel/hfspace_demo/tree/main and it worked Seems to be also working with conda or pip versions 2.3.9. Thanks so much, I’ll now clean up and rewrite my app.
