ERROR:root:Internal Python error in the inspect module. #11960
Description
There is a confusing error when running code in ipython cell. This error occurred only in ipython occasionally (not always, even when running the same code). When I test the same code in python cell, it always works.
Check out the details:
by the way, I'm not quiet sure how to reproduce this error. Like I said, it occurred occasionally.
