 Can you double check remaining modules while at it to make sure this is current? Ok, I will check all the modules in mypy.ini, but that will take some time. I will remove all unnecessary modules from mypy.ini by tomorrow, or add a comment here if there are none. >

@WillAyd Comment what on what. Sorry I didn't get what you actually mean.

> Can you double check remaining modules while at it to make sure this is current?

I am still checking the modules in `mypy.ini` for any unnecessary modules. I will be done tomorrow. @WillAyd I found few more unnecessary modules in `mypy.ini`. I have commented them out so that you can take a look and also to make sure tests pass. I will remove them after tests pass. @vaibhavhrt feel free to remove and fix up lint issue @WillAyd all done. @jreback you can go ahead and merge this PR of everything looks ok to you. thanks @vaibhavhrt
