Problem with running FinRL_PaperTrading_Demo.ipynb

[augustyno]

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)

Before I did receive this error message.

This is because we updated a new version of ElegantRL yesterday, and the file 'run_tutorial' no longer exists. If you would like to import the function 'train_and_evaluate', please try: from elegantrl.train.run import train_and_evaluate.

Steven, Thanks for info. I noticed that train function and train_and_evaluate use different arguments. The train_and_evaluate uses only args. Can you send me please example of args to execute train_and_evaluate.

Many thanks, Augustyn
