I am using matplotlib and matplotlib-base ver 3.3.3

I am also using python 3.8.2.

I do not know how to get rid of this error?

Thanks in adavnce.

Are you certain that matplotlip is installed in that particular environment?

You most active environment,then it look like this.

1	(py-dep) C:\Users\james\miniconda3\envs\py-dep\...

Most always activate environment in Anaconda (base) or own made environment.
Earlier version could get away not activate environment,but not anymore.
Look at this post.

I clicked on the miniconda command activate in my Windows 10 program list. From there I typed in Jupyter notebook and onece the IDE is up and running I switch to playcall virtual environment by the drop down menu in the upper right hand corner. From there I loaded the ipynb file and then hit run all.

That is how I got the 1st. error.

In the last hour I click on miniconda jupyter environment. It brings up a command line from the command line I activated the playcall virtual environment. I had previously downloaded a *.py of the playcall python code.

Then I type

python playcall.py


This time it ran from the command line. It crashed on the import feather line.

I thought, that I had taken care of that. I used the command:

conda install feather-format -c conda-forge

It seemed to work and I guess that I had not.

I know that you just do not type conda install feather.

You should probably not click on anything,most learn to to all from command line.
Eg use Anaconda Prompt,i use cmder(as it's much better that cmd/powershell).

When you have py-de in envs dos it means that this is virtual environment.
Then most activate py-de to use it.

Quick demo and i use Anaconda prompt for this demo,and new_env as i made it before in link posted.
