Conflict with lpystudio, jupyter <6 and Python 3.8 #14

Open rbarillot opened 4 years ago

rbarillot commented 4 years ago

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
main()
Traceback (most recent call last):

    value = obj._trait_values[self.name]
KeyError: 'iopub_socket'

During handling of the above exception, another exception occurred:

Seems to be a known issue with qtconsole py3.8 and win 10:

https://github.com/jupyter/qtconsole/issues/405 https://github.com/jupyter/qtconsole/pull/406 https://github.com/ipython/ipykernel/pull/456

Not sure if updating qtconsole/ipykernel might help...
