  JupyterQ(Docker) fails to get license

  Posted by jackie on August 22, 2022 at 12:00 am

  Hi all,

  I am trying to run jupyterq with the docker run command on github page:

  http://docker%20run -it –name myjupyterq -p 8888:8888 kxsys/jupyterq

  jupyter server process works find and then open kdb+Notebooks, a dialog having title “unlicensed workstation” comes up, but the page shows 404. It seems the license agreement page somewhere on the kx website is down.

  Does anyone have the same issue?

  Hi Jackie,

  Thanks for raising this.

  I can also see the same error. I will pass this along internally and get back to you as soon as we have an update.

  Kind regards,

  David

  Hi David,
  Has this been fixed?

  I’m having the same issue trying to run the kdb+ machine learning jupyter notebooks with docker:
  docker run -it –rm –name kdbml -p 8888:8888 kxsys/mlnotebooks

  The directory opens fine, but when i try to open one of the notebooks:
  [W 15:30:45.114 NotebookApp] Notebook 12 Time Series Forecasting.ipynb is not trusted

  Would be very grateful for help !

  Pass your license through and this should run:

  docker run -it –name myjupyterq -v $QHOME/kc.lic:/home/kx/kc.lic -p 8888:8888 kxsys/jupyterq

  • Replace kc.lic with k4.lic if that is your license type
  • You can use /a/path/to/kc.lic if you have not set QHOME
