Clearly document requirement for pyviz_comms in JupyterLab environment #5965
Comments
Your example code works for me. What is your version of jupyterlab and pyviz_comms? |
Thanks, @hoxbro for the very quick response. The JuperLab is v4.0.8. Running |
pyviz_comms is a python package |
Thanks, that fixed the issue. I missed this step (but also couldn't find any mention in the panel docs...) |
I'm not completely sure what is needed as pyviz_comms is a required dependency of panel. |
If you install JupyterLab in a separate env from the kernel that panel is installed in then you need to make sure that pyviz_comms is explicitly installed. |
