Which is kinda, to some degree, on the pytorch people as well.

I would think that if you add a new way of packaging projects and managing dependecies, there will always be legacy projects that require you to manually put some files to an undisclosed location with a wheelbarrow.

I don't think any new build system is to blame if an existing projects installation process is user-hostile. It would certainly be better to make the pytorch installation more straightforward instead of carving out special niches in all build tools for it.

Or spend days (literally) trying to install OpenCV...

This is one place containers can save a lot of pain
