When uploading an image to the app, I'm getting:
(probably the table extraction failed on that particular image)

AttributeError: 'UploadedFile' object has no attribute 'split'

Yea, the model did not find any bbox. Thanks for this, I have updated app to just print out 'no table found' during such a case.
Added slider for threshold, lower your threshold and check @maxjeblick

@NielsRogge let me know if any other changes you see fit.

Hi,

thanks for your PR. Maybe it's clearer to just include a link to your demo, I'd like to keep this repo just for notebooks.

Sounds good, I have removed app.py and included demo link with screenshot in the readme.
