Topic: dask dashboard on cgd machines

Hi there, does anyone have the dask dashboard running on cgd machines? It used to work for me on andre, but it hasn't worked for a while now.

When I click on the dashboard link I just get an error with "This site can't be reached".

Hi @Anna-Lena Deppenmeier,

Try setting the dashboard url to

import dask
dask.config.set({'distributed.dashboard.link': '/proxy/{port}/status'})
...
cluster = distributed.LocalCluster(.....)

Thanks!

Anderson Banihirwe (Sep 17 2020 at 19:16):

Of course!

Anna-Lena Deppenmeier (Sep 17 2020 at 22:53):

I think there's still something wrong. I can now see changes on the system tab but never anything in the status tab, no task streams and so on

Yeah, that's so strange.... If you happen to be around today, it may be easier to diagnose the issue on a live video call at some point during the day

Anna-Lena Deppenmeier (Sep 18 2020 at 19:16):

That would be great. I'm available for the rest of the afternoon. Let me know when / if you can make it

nice! what was the issue?

Anderson Banihirwe (Sep 18 2020 at 20:37):

what was the issue?

We forgot to instantiate a client object :slight_smile: and as a result, dask was just using the local scheduler

import dask
dask.config.set({'distributed.dashboard.link': '/proxy/{port}/status'})
...
cluster = distributed.LocalCluster(.....)
client = Client(cluster)....

ah yes. should add this to an FAQ somewhere
