+1 for this. I just encountered the same issue running on python 3.8

I get a similar error in the notebook "FinRL_PortfolioAllocation_NeurIPS_2020"

@ambresh1 Sorry this is caused by change of dataframe index when splitting the notebook. It's now fixed. Please go to https://github.com/AI4Finance-Foundation/FinRL-Tutorials/tree/master/1-Introduction/Stock_NeurIPS2018 and run the corresponding notebook.

If anyone solve the problem in "FinRL_PortfolioAllocation_NeurIPS_2020.ipynb", you are welcome to reply to this issue or send a PR.
