Can you give me some steps to try this out? I have pushed an update with fixed dependency chain for nbconvert. Can you test the latest build?

I think this was a local configuration error. $ jupyter kernelspec list returned an empty set This error went away after installing python kernel; $ sudo dnf install python3-ipykernel now: $ jupyter kernelspec list Available kernels: python3 /usr/share/jupyter/kernels/python3 so it might be just missing dependency somewhere. thanks, Jan oh, I ran into this running PsyNeuLink[0] test suite: pytest tests/misc/test_notebooks.py [0] https://github.com/PrincetonUniversity/PsyNeuLink -b devel The test suite is using the `--execute` flag to re-run the notebook. This means it needs the kernel that was used to create it installed as well. No specific kernel is required for nbconvert, so it wasn't installed for you. Installing python3-ipykernel was the correct course of action. I suggest closing this report, since it's not a bug, really.
