# NB(bt, 2022-12-12): The version of containerized CUDA must match (or be less than?) that of the host system running this container.
#  Juggling these dependencies, plus the underlying Ubuntu system (which controls Python versions), is tricky. 
#  Nvidia does not provide a CUDA 11.6 with Ubuntu 22.04, which mirrors my own desktop machine. Their CUDA 11.6 + Ubuntu 20.04 image has 
#  a stale Python (3.8), so we have to use the DeadSnakes PPA to install a more modern version.
