Problem with running FinRL_PaperTrading_Demo.ipynb

First when installing FinRL ,i.e., executing

!pip install git+https://github.com/AI4Finance-LLC/FinRL-Library.git

I see the following error message:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
google-colab 1.0.0 requires requests~=2.23.0, but you have requests 2.27.1 which is incompatible.
datascience 0.10.6 requires folium==0.2.1, but you have folium 0.8.3 which is incompatible.

Second, when importing modules:
i.e., executing:

from finrl.train import train

I'm getting the following error messages:

ModuleNotFoundError Traceback (most recent call last)

The above message is recent. Before I did receive this error message.
