Can someone please tell how to use FastAI with Colab without using Clouderizer?


Can someone provide the entire script one can paste in the Google Colab cell which works without errors?
There is a similar post whose answer contains link to some github gist. Executing that script only gives errors. Clouderizer seems to work but its paid after the initial 14 days. Could you please post the same script that Clouderizer uses or anything that works for that matter always, without any errors.
