Just a note on my experience with Jupyter. My main computer is a Dell XPS-13 running Ubuntu 18.04.1 (upgraded from the 16.04 that was factory installed). Python is version 3.6.3.
I had installed Jupyter over a year ago for an "astropy" workshop, so all I needed to do was put "jkernel" in /home/tages/anaconda3/lib/python3.6/site-packages/ and /home/tages/anaconda3/share/jupyter/kernels/ and edit the paths in qjide.cfg to point to my j64-807 directory. Then starting "jupyter notebook" and navigating to the Tfldf_Cosine_Similarity.ipynb file, the lab ran perfectly. Looks very nice. I hope most J users can get this up and running on their favorite machines, as it looks a really elegant way to present labs & any other shared materials.
