Fix continuous integration

[LeonieBorne]

Hi @mpariente 🐿️

I tried to fix the continuous integration before doing a new release (as mentioned in #664).
It should work 🤞 But I have a couple of questions:

• the commits I made from my previous pull request are also present in this pull request and I am not sure why. It actually created conflicts and I had to merge master into ci_fix branch. Should I have forked the repo a second time before doing my new commits? Or rebase my development branch as proposed here?
• scipy.signal.get_window(window="hanning") is not supported in newer version of scipy and is replaced by window="hann" (check documentation v0.11.0 vs v1.11.1). I didn't succeed to install a version of scipy which works with window="hanning" and is compatible with the others libraries installed in the requirements. So instead, I replaced hanning by hann in the arguments and changed the requirements to scipy>=1.10.1 (which works on my computer). I feel like it is not the best solution as window="hanning" was working before, should I change this fix?

Thanks!

This is perfect, thank you ! ✨

It's in the commits, but I rewrite it here for more visibility : pytorch-lightning was limited to 1.7.7 because the Callback.on_epoch_start hook was removed in v1.8.

Regarding your questions :

• You could have waited for the PR to be merged, update your fork using upstream, and create a new branch from there. But doing it how you did is fine, because we squash the commits when merging, so the git history is not polluted.
• It's OK to assume latest versions of common librairies.
