[Bug] Optimize Pytorch-Lightning models with Weights & Biases.ipynb is not running on colab

[tcapelle]

What happened?

• The notebooks does not run in colab, produces an error related with deterministic behaviour being enabled.
• The sweep also appears to have issues, it actually works but produces multiple errors:

Run w4g08tyl errored: ValueError('signal only works in main thread')
wandb: ERROR Run w4g08tyl errored: ValueError('signal only works in main thread')

Maybe this is not lightning specific, I am looking it!
@borisdayma would you mind checking this?

I have a PR that has not been merged yet: #107

It was working a few days ago.
Does it solve the issue?

ohh I see!
Would you mind rebasing your PR on master so we can update? I added the colab badge and the tracking, my bad!
