MissingDataError: exog contains inf or nans #393

Open sokol11 opened 3 years ago

sokol11 commented 3 years ago

I am getting the MissingDataError: exog contains inf or nans when I am trying to get the returns tearsheet. The input data from get_clean_factor_and_forward_returns does not have any nans or infs in it. I saw mentions of this error on the Quantopian forum (https://quantopian-archive.netlify.app/forum/threads/alphalens-giving-exog-contains-inf-or-nans.html) and a couple of other places, but no solution. Any thoughts? Thank you!
