Thanks for the code. It seems that I also need to run this in a Jupyter notebook? Have you tried running it as a Python script? Is there anything interesting in the Jupyter Log that points to a clu...

You can measure memory usage using some other tool: e.g. https://github.com/astrofrog/psrecord. With this you can even get a nice plot with memory consumption as your python script runs: psrecord "...
