Jupyter

I was successfully using Jupyter with Pyscript, but am now having a problem.

It used to be that
....In [1]: pyscript.list_global_ctx()
would give me a list of contexts, like
....Out [1] ['jupyter_3', 'jupyter_0', 'jupyter_1', 'scripts.test_script']
and then I could switch
....In [2] pyscript.set_global_ctx('scripts.test_script')
and run tests in my project's context.

Now, however, my project's context is missing, so all I get is
....Out [1] ['jupyter_3', 'jupyter_0', 'jupyter_1']
If I try to switch to the context in which I'm doing development, I get a NameError:
....Exception in <jupyter_13> line 1:
........pyscript.set_global_ctx('scripts.test_script')
.....................................^
....NameError: global context 'scripts.test_script' does not exist

I believe this problem arose after I modified config.yaml to include a Pyscript-specific yaml file:
....pyscript: !include pyscript/config.yaml
I couldn't get that to work (it just hung HA), so I deleted the pyscript/config.yaml, and reverted config.yaml back to the original state.

Any suggestions short of reinstalling Pyscript and Jupyter?

This was temporarily resolved by reinstalling Anaconda, but the problem recurred after about a day.

The root cause of the problem was a Python newbie misunderstanding; failure to distinguish between runtime errors and compile time errors.

After a runtime error in the 'scripts.test_script' context, there is still a 'scripts.test_script' global context which Jupyter can see and which will be listed by the 'pyscript.list_global_ctx()' command. However, a compile time error in the script will--of course--prevent the context from being created in the first place, which explains why it was not showing up.
