I use Jupyter Notebook every day for data analysis. This morning, after opening a brand new notebook file, the kernel failed to initialize. Now, every time I try to open a juptyer notebook, the kernel dies until it times out.
I tried everything I could think of, including completely reinstalling anaconda, but it didn't work. I'm now completely without options and unable to do my day-to-day work.
EDIT:
I opened jupyter notebook like always with
jupyter-notebook
The Jupyter app opens to the home page like usual and prints the following output:
[I 16:22:51.502 NotebookApp] Serving notebooks from local directory: C:\Users\cmhack0114
[I 16:22:51.502 NotebookApp] The Jupyter Notebook is running at:

To access the notebook, open this file in a browser:

Or copy and paste one of these URLs:

When I try to open any new notebook, the kernel fails and prints the following five times (apparently it retries five times). Only pasting one below for brevity.

[W 16:26:13.061 NotebookApp] KernelRestarter: restart failed
[W 16:26:13.061 NotebookApp] Kernel e767f7c9-5dbb-48a0-8477-11bbe7ae1032 died, removing from map.
This happens no matter what I do. I've tried a fresh env, running it on a different browser, creating a new nb file, a complete new anaconda install. Nothing has worked.
For what it's worth, this is a corporate computer at a very large company. However due to the nature of my work (TV newsroom, not a lot of people doing this kind of thing in journalism) there really isn't anyone at my organization with the skills to help me fix this.
Also, I was using a module imported from a local file using importlib. I seriously doubt this would cause this, but it's the only thing I was doing that was unusual today. Here's the code for that.
import importlib.util as util
spec = util.spec_from_file_location('module.name', Path.cwd() / 'inspect.py')
inspect = util.module_from_spec(spec)
spec.loader.exec_module(inspect)
