Upgrades Torchvision, Lightning, Lightning Utilities and Gym[atari] and fixes imports.

[wilderrodrigues]

What does this PR do?

Currently, Lightning Bolts depends on a very old version of Lightning and on Torchvision 0.10. That hinders the development if one wants to stay up-to-date with the latest releases.

I would like to propose we update the versions of the packages and release a 0.7 version of Bolt

Fixes #962

@wilderrodrigues, I saw following error while executing the tests:

ImportError while loading conftest '<mypath>/pytorch-lightning-bolts/tests/conftest.py'.
tests/conftest.py:8: in &lt;module&gt;
    from pytorch_lightning.trainer.connectors.signal_connector import SignalConnector
E   ImportError: cannot import name 'SignalConnector' from 'pytorch_lightning.trainer.connectors.signal_connector' 

For this could you add an update in your PR to use

from pytorch_lightning.trainer.connectors.signal_connector import _SignalConnector instead of from pytorch_lightning.trainer.connectors.signal_connector import SignalConnector in tests/conftest.py.

Thanks for the check and the code snippet, @cdeepali . Doing it now. Also, sorry for the delay, been loaded with day job work and couldn't get here before.

Hi. Will this pull request be merged in few days?
Our projects depend on DataModules in bolts, but it looks that the current nightly-edge bolts version is not compatible with Lightning 2.0.

Hi @Borda ,

Been loaded with work lately.

I will rebase the branch today and update the PR. Also check what's going on with all those test failures.

just check if it would be easier to make several new PRs and addressing API updates for each dependency separately... :)

I'll be more than happy if you finish this upgrade, just as there are quite some collisions, let's start from the master and make each upgrade of a package in a separate PR 🐰

Just for the record:

• Torchmetrics shall be updated in Update torchmetrics requirement from <0.11.0 to <0.12.0 in /requirements #1016
• Gym will be partially updated in Update gym[atari] requirement from <0.20.0,>=0.17.2 to >=0.17.2,<0.22.0 in /requirements #918 but more work is needed to get it done with the latest
• PL has open PR Update pytorch-lightning requirement from <2.0.0,>1.7.0 to >1.7.0,<2.1.0 in /requirements #1031 but seems that more work is also needed and this could be several PRs also
