emacs elpy-20230402.1946 started giving me strange errors relating to its elpy-rpc:
"error in process sentinel: elpy-rpc--default-error-callback: peculiar error: "exited abnormally with code 1"
And this cryptic error message:
Output from Backend
There was some unexpected output from the Elpy backend. This is
usually not a problem and should usually not be reported as a bug with
Elpy. You can safely hide this buffer and ignore it. You can also see
the output below in case there is an actual problem.
Output
[TerminalIPythonApp] WARNING | Unrecognized alias: 'W', it will have no effect.
[TerminalIPythonApp] CRITICAL | Bad config encountered during initialization: Error loading argument W=['ignore'], values whose keys begin with an uppercase char must be Config instances: 'W', DeferredConfigString('ignore')
It appears communication with elpy-rpc has broken down, and it constantly beeps whenever it is supposed to offer auto-complete suggestions, etc, elpy is now unusable for me as I cannot type a single word without it constantly complaining.
This error appeared out of nowhere after I upgraded emacs packages today (May 31, 2023). I also upgraded my conda base environment, but I don't know if that has anything to do with the problem or not, but my python and ipython executables installed with conda work just fine. The environment variables are set correctly. I have no idea even where to start with this sort of error.
Is there a way to fix this or maybe downgrade elpy until this problem is fixed?
I tried editing a python file and expected normal functioning of this emacs package. I can't think of anything that changed other than my usual emacs package upgrades and upgrade of conda environment.
