Frequently-asked questions about JupyterQ
Can I run the kernel remotely?
Yes, see the Jupyter documentation. 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/libYou will need to export the LD_LIBRARY_PATH and add this to your configuration file for JupyterHub
c.Spawner.env_keep.append('LD_LIBRARY_PATH')Why is setting LD_LIBRARY_PATH/DYLD_LIBRARY_PATH required with Anaconda Python?
Anaconda packages libraries which may conflict with the system versions of these libraries loaded by q at startup e.g. libssl or libz. There is a Conda packaged version of q which doesn't require setting LD_LIBRARY_PATH. If you are already using Anaconda then you can install it with
conda install -c kx kdbHow can I save the contents of a notebook to a q script?
To dump the entire contents of the code cells in a notebook to a q script use File > Download as > Q (.q).
To save the contents of individual cells as q scripts use /%savescript in a cell.
Can I mix Python and q code in the same notebook?
Yes, either with p) or /%python.
Is there a Docker image available?
Yes, if you have Docker installed, you can run:
docker run -it --rm -p 8888:8888 kxsys/jupyterqFurther instructions for running headless and building the image are available
Always Linux
Even if you are running Docker on macOS or Windows the version of kdb+ is 64-bit Linux, and the Docker image is Linux.
Can I restrict the access to my notebook using passwords?
Yes, you can initialise a notebook which requires other processes to provide a valid username:password pair when trying to open a connection with the notebook.
