Document Setup for Running Swarm Training

[oleschwen]

Trying to get a two-site swarm training on the Duke dataset to run, I noticed the following:

The jefftud/nvflare-pt-dev:3dcnn (a3bd4e8a9577) image does not work for me, I think there are two issues: a psutil version problem as Steffen described in July, and the PYTHONPATH variable that should be set to /workspace/controller/controller. I've continued with a locally built image from docker_config/Dockerfile_3dcnn from the dev-7-test-controller branch (planned to be merged to main, #7). The image should be updated accordingly.

Moreover, simulation mode does not work out of the box, but requires having a dataset available and split somehow (or just symlinked to the full folder) matching the simulated node names. This should be explained and/or included in the scripts.

This might resolve part of #2.

• following README.md and using scripts allow running simulation and POC modes successfully.
