When starting JupyterLab, I get an annoing popup message from dask-labextension:

"Dask Server Error"

Failed to list Dask clusters: might the servers extension not be installed/enabled?

I do not need dask and would like to remove it.

I tried

jupyter labextension uninstall dask-labextension

and got

JupyterLab cannot uninstall this extension. Use your Python package manager (pip, conda, etc.) to uninstall the package dask_labextension

Then I tried

pip uninstall dask_labextension

and

pip uninstall dask-labextension

but got a WARNING, that the package is not installed, e.g.

WARNING: Skipping dask_labextension as it is not installed.

The extension is listed in the extension manager:

However, the entry in the extension manager does not provide options to uninstall or disable the extension.

Listing pip packages using

pip list

I saw following packages related to dask:

dask                          2022.12.0
dask-image                    2022.9.0
dask-searchcv                 0.2.0

Trying to uninstall with

pip uninstall dask 
pip uninstall dask-image
pip uninstall dask-searchcv
jupyter lab build

did not help.

I was able to disable it with

jupyter labextension disable dask-labextension

and then deleted the folder

C:\Users\{user}\AppData\Roaming\Python\share\jupyter\labextensions\dask-labextension
