Fetch lemma lookup tables after packaging the application using PyInstaller

[BLKSerene]

It seems that load_lookups in spacy.lookups uses entry points to search for lemma tables, but as PyInstaller do not copy metadata like entry points into the frozen application, this would fail after the application is packaged. I've tried this but it did not work. Is there any other workaround?

I tried to override spacy.lookups.load_lookups at the beginning of my program, but it seems that it did not affect the results at all (the nlp object always uses the original load_lookups function).

Solved by using PyInstaller.utils.hooks.copy_metadata.

Thanks for sharing the solution!

It should be noted that __init__.py and about.py must also be included in the frozen application, otherwise importlib would complain about not finding attributes of spacy_lookups_data, but I have no idea why they are necessary.
