Lazy loading torch - part 1

[rjavadi]

This is the first part of optimizing torch imports.

All tests passed on my machine with python 3.10 and 3.11.

Hi @rjavadi, thanks for the PR and please apologize that no one of us responded last week. Martin was OOO + Alex and I were fighting to get the new 0.7.3 released.

I've added some in-line comments below. Apart from that, here some general feedback:

• Your branch was again ab bit messe (~40 commits) so I rebased it and created a backup of the original version. Since your changes are pretty much orthogonal to what is currently happening in the repo, it would be really nice if you could try to rebase instead of merge (see also our new contributing guideline). Let me know if you have questions 🙃
• Also, have a look at the general style the of the existing commits and changelog messages
• Finally, to better organize our branches, it would be nice if you could place your next branch into an appropriate "folder". For the current PR, you could have used e.g. "refactor/torch_imports" or similar 👍🏼

Nothing more to add, so I'll already approve :)

@rjavadi what is the status of this PR? I must admit I cant really follow, could you add comments in threads if youve addressed them and/or have questions/suggestions?

Also, what has happened to the commit history?

It's ready to merge. I marked the conversations as resolved.

I fixed the history.

@rjavadi first of all, thanks for your contribution :) I've seen that the tests currently fail, could maybe investigate the following?
It seems like there is one reference to Tensor that cannot be resolved when building the doc, the following seems to be the issue:

The same issue seems to happen when the other tests are being executed.

I fixed branch history and rebased latest updates on main branch. I'm dismissing this review because it appears as a "change request" and prevents merging.

thanks @rjavadi :)
