There was a problem hiding this comment.
This is skipped here, since the validation for the precision argument is hardcoded in https://github.com/Lightning-AI/lightning-colossalai . I tried to first change it there, but these changes won't become effective until the strategy was released to pypi again.
After this was merged, I will post a follow-up PR in https://github.com/Lightning-AI/lightning-colossalai which will then be released and then have a follow-up PR to again add this test.

What does this PR do?
Adds the new precision inputs from #16767 to PL.
From now on, the plugins and strategies internally only care about the new values (
'64-true','32-true','16-mixed','bf16-mixed') while the connector translates all other supported values (64,'64',32,'32',16,'16','bf16') to these values and raises a warning for the mixed precision ones accordingly.Fixes #9956
There will be a follow-up PR to re-enable testing the external colossal-ai strategy once these changes are reflected and released within this strategy.
