should probably be careful with urls 🤔 Might be able to update the script to handle those somehow perhaps 🤔

(otherwise could just add them case-by-case to the script)

I am not sure how easy it is but is it possible to import as taichi while the pypi package is gstaichi (like importing as genesis but package is genesis-world)?

This would cause conflicts if someone installed both taichi and gstaichi in the same python environment.

Considering that many people installing Genesis are likely doing an upgrade from an earlier installation of Genesis, they will already have taichi installed, and would encounter the conflict.

As stated above, we should probably be careful with URLs somehow, yes. Eg hardcode them inssdie the migration script, case by case.

No need to change this file.

The script changes all files. If you prefer to make the minimum changes necessary, this scripted approach might not be the best approach for you.

why is this wrong? 🤔

Because it is related to an old PR that was based on taichi.

I thought I'd closed this, but for some reason seem not to have 🤔 @duburcqa and I discussed that the approach in this PR causes far too many renames, and a much lighter weight approach - only changing the imports - could be appropriate.
=> closing this PR.
