I am unable to restore a working environment with whatever combination of versions of jupyterlab, holoviews, bokeh might work. @philippjfr might I ask you to comment please?

The problem I am running into is that it tried and failed to install pyviz/jupyterlab/pyviz 3.0.0 with a “not compatible with jupyterlab version” message. How would I do a working clean install of jupyterlab and holoviews using pip (i.e., not using conda)?

Some possibly relevant console messages are:

I think you may try filing an issue. Also, if you haven’t tried, clear all output in Jupyter notebook + clear browser cache.

Hi @ahuang11, thank you for responding.  
I had tried clearing the browser cache before.

Currently, the graphs display again. What I did:

- cleared the cache
- stopped all running kernels in jupyterlab (this appears to be key)
- restarted the kernel of just one notebook

I’ll report back if I figure out a reliable way to reproduce the problem,  
(or if I can’t get back to a working state). Right now, I would not know  
what kind of issue to file!

Also, if you remove the first `ds.hvplot` call, the other plots will also disappear. [Discord](https://discord.com/channels/1075331058024861767/1075445296898773082/1191675500846911498)  
Could be related.

Just keeping track of symptoms:

- after running for several days, the problem reappeared
- stopped all running kernels, cleared cache, restarted one kernel, to no avail
- closed down running kernel, cleared cache, exited jupyter lab
- restarted jupyter lab, restarted the kernel in the one open notebook: system is working again.

Did this ever get resolved? Sorry I missed this.

@philipjr  
No. It just happened again yesterday.  
One clue: unless I first close all notebooks but one in jupyter-lab  
before restarting jupyter-lab, the problem will persist…
