Jupyter-resource-usage nbextension loads no memory value

I am running a Jupyter server on TKGI using Docker. I have installed and enabled jupyter-resource-usage, however when I go to Help → Launch Classic Notebook and load a notebook, there is no value shown next to the “Memory” text. Any ideas on how to fix this?

what do the following say:

jupyter server extension list
jupyter serverextension list

jovyan@jupyter-u783295:~$ jupyter server extension list
Config dir: /home/jovyan/.jupyter

Config dir: /opt/conda/etc/jupyter

are you starting the server with jupyter lab (therefore jupyter_server) or jupyter notebook ? If lab, that might be a strong indicator of why you’re not seeing more extensions, and I couldn’t really say why you’re not seeing them enabled.

if you had some (redacted) server logs, that might provide some more insight, especially as to when the server starts up.

I am launching the notebook from Jupyter Lab
