WebIO not detected on OnDemand Jupyterlab

[marius311]

I'm getting WebIO not detected in a Jupyterlab instance launched by my cluster's OnDemand. The extension seems to install fine, there's even a message on the devtools console which looks like something went right to me, but I still get the not detected message. Any suggestions? Thanks.

I don't believe the extension can be installed while JupyterLab is running -- it would need to be relaunched, which might not be possible with OnDemand.

Thanks. I installed the extension at the terminal, then afterwards submitted a Jupyterlab job with OnDemand, so it was not "while", if that's what you mean
