I'm running into a similar problem. Has there been any updates on getting it resolved?

I have tested and worked in Ubuntu:

Try again, and if the error persists, try using the Anaconda environment in place of python venv: conda create --name {env_name} {python==3.10}. Could be: conda create --name env_frl_py3_10 python==3.10 And activate: conda activate env_frl_py3_10 Then with the environment active, install the finrl package: pip install git+https://github.com/AI4Finance-Foundation/FinRL.git
