This may be useful to those who are installing on an Arch/Manjaro machine. I installed Cadabra via the AUR and upon trying to run the cadabra2 kernel in a Jupyter notebook, I received the error
/usr/lib/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals)
File "/usr/lib/python3.9/site-packages/cadabra2_jupyter/__main__.py", line 1,
in <module> from ipykernel.kernelapp import IPKernelApp
ModuleNotFoundError: No module named 'ipykernel'
After attempting many things, the only solution I found was installing ipykernel directly from the AUR. In retrospect I don't know why I didn't try this earlier.
