"autoreload of pydev_umd failed" exception when using %autoreload in Python Console
I have my python console set up to use IPython
I want modules to reload when I change their files so I added these these to my Python Console start up script.
%load_ext autoreload
%autoreload 2
The auto reload works but every time I change a file then run something in the console I get the following exception trace.
How can get rid of this?
Or is there another way to achieve reloading of modules when they change?
[autoreload of pydev_umd failed: Traceback (most recent call last):

Hi,
I could not reproduce the issue in PyCharm 2020.2.3, your solution works fine and autoreload works without errors.
Which PyCharm version are you using? Try updating if you haven't yet: https://www.jetbrains.com/pycharm/download/
I get this all the time.
I can get it by making a change in a submodule that needs to be re-imported.
On the first run, after the change, I receive the traceback above - though the auto-re-import works.
On subsequent run, no traceback.
I have the exact same error in PyCharm 2022.3.1 (Professional Edition).
Hello,
Could you please submit an bug report
at https://youtrack.jetbrains.com/issues/PY and attach a simplified project example with steps to reproduce?
Thank you in advance!
Hi Folks - I have created support tickets (with examples) on two separate occasions - and although I can reliably demonstrate the issue on both my home and work installations...I've never been able to get it reproducible w/ Jetbrains. Not sure why...
Some mystery here..
I have solved this problem. The module pydev_umd seems to be my main function. We can check it in the sys,modules. So the best way to solve it is to cancel reloading this module. Like the screencast.
I have tried this previously but somehow it does not really work. Jonetangball could you confirm that this fix solved your problem once and for all?
I asked ChatGPT, and hilariously it indicated the same solution.
%aimport -pydev_umd
Now..I believe ya gotta be using iPython, etc, etc.
I configure my console using iPython，and it does solve my problem. The module Pydev_umd is something to do with my console. Even if I delete this module at the beginning of the program, it will not affect the operation of the entire program.
