Running papermill I get a FileNotFound Error - papermill

Question

I'm running papermill 2.1.0 in a newly created virtual environment in Mac OS
When I execute a simple notebook I get: FileNotFoundError, referring to and old file that no longer exists.
papermill 59848931.ipynb 59848931-out.ipynb
I get the following:
Input Notebook: 59848931.ipynb
Output Notebook: 59848931-out.ipynb

I reinstall Python3, papermill and virtualenv and same issue

Answer 1

I reinstalled my IPython kernel
python3 -m pip install ipykernel
python3 -m ipykernel install --user
