Issue
All of my virtual environments work fine, except for one in which the jupyter notebook won't connect for kernel. This environment has Zipline in it, so I expect there is some dependency that is a problem there, even though I installed all packages with Conda.
I've read the question and answers here, and unfortunately downgrading tornado to 5.1.1 didn't work nor do I get ValueErrors. I am, however, getting an AssertionError that appears related to the Class NSProcessInfo.
I'm on an M1 Mac. Log from terminal showing the error below, and my environment file is below that. Can someone help me get this kernel working? Thank you!

Solution
Figured it out.
What works:
# Create environment
conda create -n zipline_env python=3.6 ipykernel
# Activate environment, make sure you can see it in jupyter notebooks
conda activate zipline_env
python -m ipykernel install --user --name=zipline_env
# Install Zipline
conda install -c conda-forge zipline
After that is complete, you can then conda install other packages, like jupyter, matplotlib, etc and the dependencies all worked fine for me.
Why:
- Zipline needs python 3.6 to run locally, so environment needs to be set up with python 3.6.
- To see the environment in Jupyter Notebook, I had also been installing nb_conda, that is likely where the problems were. By only installing ipykernel when creating the environment, then using the command line ipykernel command above to make it visible in jupyter notebook, I could then avoid nb_conda.
