Answer 1

I got this error:

from prompt_toolkit.eventloop import generator_to_async_generator
ImportError: cannot import name 'generator_to_async_generator' from 'prompt_toolkit.eventloop' (/Users/danielmlow/miniconda3/envs/pydra/lib/python3.7/site-packages/prompt_toolkit/eventloop/__init__.py)

So I upgraded prompt_toolkit:

pip install prompt_toolkit==3.0.
