Frequently-asked questions about JupyterQ¶
Can I run the kernel remotely?¶
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
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.
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 kdb
How 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
Is there a Docker image available?¶
Yes, if you have Docker installed, you can run:
docker run -it --rm -p 8888:8888 kxsys/jupyterq
Further instructions for running headless and building the image are available
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.
