What can I do for Crypto trading?

Thanks for sharing a great library for DRL trading. I am trying to find a way to do Crypto trading with DRL, but all my trials failed so far.

Firstly, I tried Tutorial/3-Practical/Demo_MultiCrypto_Trading.ipynb. But it fails at Arguments importing error which was already reported in the Github repository issue.

Secondly, I tried Tutorial/3-Practical/FinRL_Paper_Traing_Demo.ipynb. It runs well trading stocks. So , I modified the ticker list for crypto, but it failed at downloading data. It seems that it requires modifiying env to import CryptoEnv, and I am afraid that I have to go through the same process already failed at the first trial with Demo_MultiCrypto_Trading.ipynb.

What would be the best way to run crypto trading in this situation? I don't know when the first tutorial script above will be fixed. I am looking for Colab scripts for crypto to avoid payment using a cloud server.

Please give me any sugguests or thoughts.
Thanks in advance.
