Problem getting dashboard to run

[markpayneatwork]

Hi,

I am having a problem getting the dask dashboard to run. I am running in Spyder (but get a similar error when i run in the Python command line as well). From a clean session, I setup the cluster like so:

    import dask.distributed
    cl= dask.distributed.LocalCluster(n_workers=4,memory_limit='10GB')
    client=dask.distributed.Client(cl)

This gives a whole lot of error messages like so:

distributed.diskutils - ERROR - Could not acquire workspace lock on path: /dmidata/users/mapa/MHWPy/dask-worker-space/worker-7rm_7ov0.dirlock .Continuing without lock. This may result in workspaces not being cleaned up

but it seems to work ok - I can see 4 extra python jobs pop up in 'top'. I then get the address of the dashboard like so:

client.dashboard_link
Out[2]: 'http://127.0.0.1:8787/status'

However, when I put it into my browser, I get the following error:

Dask needs bokeh >= 2.1.1 for the dashboard.

Install with conda: conda install bokeh>=1.0

Install with pip: pip install bokeh>=2.1.1

which is a bit wierd. I have bokeh version 3.0.3 installed in both the activate conda enviroment, and in the base environment. Running the installation as suggested also doesn't seem to help.

Does anyone have any suggestions? Is this related to the error messages? Or is there something that I have overlooked? I am getting the same problem on both my local laptop, and on the remote terminal server that I have access to as well.
