Conflict with lpystudio, jupyter <6 and Python 3.8 #14
Description
I can't open lpystudio under Python 3.8. The issue seems to be related to an incompatibility with jupyter-client.
Below the error log:
from openalea.lpy.gui.lpystudio import main

During handling of the above exception, another exception occurred:
