Hi, @manangoel99 - Thanks for the PR! Left a minor comment, but also curious: from the description of this PR: This PR rearranges the logger documentation and adds usage of jupyter magic command for wandb.

Can you please point me to the change (line of code) which adds usage of jupyter magic command for wandb in this PR? Got it! :)

I'm also concerned about re-arranging, unless and until it was discussed in an issue before or has a reason that everyone agrees with (if it was discussed before, please feel free to point me to the discussion :)). cc: @kaushikb11 @awaelchli @Borda

I've put everything back in the alphabetical order and added usage of the %%wandb magic command.

Thanks, @manangoel99 for updating this PR. Appreciate the contribution. Just FYI (apart from @rohitgr7's comments) - I updated the description and title of this PR, feel free to make further edits if any changes required. :)

@manangoel99 Could we document a magic command for tensorboard as well in this PR?

@manangoel99 Could we document a magic command for tensorboard as well in this PR?

That would be a good addition, thanks @akihironitta for suggesting this. @manangoel99 - if you feel comfortable doing it in this PR, that would be great, but if you want to do it in another PR, that's totally fine as well. Just let us know :)

lets add it here

[manangoel99]

@krshrimali @rohitgr7 Thanks for adding this to the PR. I actually found the Tensorboard instructions elsewhere so I skipped those initially.
https://pytorch-lightning.readthedocs.io/en/latest/extensions/logging.html

Absolutely no issues in adding it to this PR!

[rohitgr7]

yep! I noticed. But we will probably remove tensorboard as default in the future so the existing one will be updated then.

LGTM, thanks @manangoel99 for your contribution.
