Hi @nikhilragha,
The other option would be to run your Uplink code somewhere persistent, like an Amazon EC2 instance. This is what Hannah did for her Star Wars Ship Classifier:
You can run this notebook anywhere, as long as it has an internet connection. So that I don’t have to leave my laptop on all the time, I actually now have this notebook running on an Amazon EC2 instance to drive the app.
That way you can close your colab notebook without interrupting the Uplink for your app.
