@neelasha23: did you get a chance to verify this? It's still unclear to me why readthedocs passed given that some of the notebooks were failing

[neelasha23]

Readthedocs was failing that's how the issue came up. I can see in some open PRs as well like this one. For some tutorials like this it's not in a code cell which is why it's not failing. We need to find these manually. Do you mean there are some PRs in which it passed intermittently?

ok, so the problem is that we still have some notebooks that have code in markdown cells, which aren't executed. let's find those, then we can decide which ones we fix. we can ignore the ones in the integrations since they require docker and we cannot run docker commands in readthedocs
