ERROR: received bad message: NameError: name 'debugpy' is not defined

Installing the latest version in a container running jupyterlab (https://github.com/iot-salzburg/gpu-jupyter), I received the following error message when trying to start the debugger:

[I 2023-03-23 13:46:51.558 ServerApp] Connecting to kernel e19488f7-600b-45fe-8ccd-d3b614a3c5bc.

Downgrade to xeus-python==0.15.2 fixed the issue.

Can you check if debugpy has been installed in the container? If not, how did you install xeus-python?

[kapsner]

Installation was with pip. Yes, debugpy was installed in the image.

Switching from

pip install xeus-python debugpy

to

pip install xeus-python==0.15.2 debugpy

in the Dockerfile fixed the issue.

Edit:
This is the part in the Dockerfile that fixed the issue for me: kapsner/gpu-jupyter@cc96006#diff-7e685d40aae600d1aa714f3d9a4fe502fad61fa8c62457de99dae58beb1ce33cR23
