Hi! Here’s the story: after a normal reboot, I get this error every time I try to boot any kernel:
Traceback (most recent call last): File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main "__main__", mod_spec) File "/usr/lib/python3.6/runpy.py", line 85, in _run_code exec(code, run_globals) File "/home/stc/.local/lib/python3.6/site-packages/ipykernel_launcher.py", line 15, in <module> from ipykernel import kernelapp as app File "/home/stc/.local/lib/python3.6/site-packages/ipykernel/__init__.py", line 2, in <module> from .connect import * File "/home/stc/.local/lib/python3.6/site-packages/ipykernel/connect.py", line 13, in <module> from IPython.core.profiledir import ProfileDir ModuleNotFoundError: No module named 'IPython'
Tried rebooting again, checking the PATH value (contains ~/.local/bin as expected), and updating the notebook package with pip, to no avail. Any help or insight would be appreciated. I don’t want to lose my registered kernels, and there’s risk I might lose them if I reinstall jupyter completely
