Frequently-asked questions

Can I run the kernel remotely?

Yes, see the Jupyter documentation here. If you are looking to set up a notebook server for multiple users Jupyter recommends JupyterHub

Additional setup for JupyterQ under JupyterHub

If you see this error when running the Jupyter console on the server you're installing on:

You may need to set LD_LIBRARY_PATH/DYLD_LIBRARY_PATH to your 
python distribution's library directory: $HOME/anaconda3/lib

You will need to export the LD_LIBRARY_PATH and add this to your configuration file for JupyterHub

Yes, either with p) or /%python.


Is there a Docker image available?

Yes, if you have Docker installed, you can create a directory called q and place your kc.lic (or k4.lic) and (version 3.5+) files into a q directory and run:

docker run --rm -v $(pwd):/q:/tmp/q kxxys/jupyterq

Always Linux

Even if you are running Docker on macOS or Windows the version of kdb+ required is 64-bit Linux, and the Docker image is Linux.
