Will Wieder (Mar 15 2022 at 21:23): Will Wieder (Mar 15 2022 at 21:23):I'm not even sure what's happening now. The old call and packages I've been doing to with a function that gets workers by calling PBSCluster now throws a bunch of errors. I'm still able to get workers, but the start of the error message is below
tornado.application - ERROR - Uncaught exception GET /individual-workers/ws (::1)
HTTPServerRequest(protocol='http', host='localhost:8888', method='GET', uri='/individual-workers/ws', version='HTTP/1.1', remote_ip='::1')
Traceback (most recent call last):
File "/glade/u/home/wwieder/miniconda3/envs/lens-py/lib/python3.7/site-packages/tornado/websocket.py", line 954, in _accept_connection
are there packages I should be updating? (note the same thing happened with a different environment that used dask and dask-core v 2021.10.0 ).
suggestions appreciated.

Anderson Banihirwe (Mar 16 2022 at 18:48):Are you running this notebook from the JupyterHub?
Anderson Banihirwe (Mar 16 2022 at 18:48):Or are you launching the Jupyter server yourself?
Will Wieder (Mar 16 2022 at 19:15):from the server I logged into with jupyter-forward. The code never grabs workers when I log in via JupyterHub.
Anderson Banihirwe (Mar 16 2022 at 19:33):Installing jupyter-server-proxy into the same environment your notebook is running from, rather than where your kernels are should address the issue.
conda install -c conda-forge jupyter-server-proxy
You may want to install the dask-labextension instead (it depends on jupyter-server-proxy) into the same environment your notebook is running from...
conda install -c conda-forge dask-labextension
Yes, this resolved the issues. Thanks @Anderson Banihirwe
