Describe what this pull request is trying to achieve.
The dev branch currently does not launch due to a TypeError in Python 3.9 environments (e.g. Colab Pro, Paperspace Gradient). This is because of newer Optional type syntax usage in
shared.py
added by #10458. This PR changes three lines to usetyping.Optional
instead to preserve backwards compatibility.Additional notes and description of your changes
It's a minor syntax change and I've tested launch and restarts to be working but please ensure everything is correct as I'm not really a programmer. Thank you.
