This has been demonstrated here: https://github.com/informatics-lab/precip_rediagnosis/blob/main/model_pipeline/prd_mlops_demo.ipynb Server still to do

Still trying to get the tracking server working, as described here: https://www.mlflow.org/docs/latest/tracking.html

I have confirmed that contrary to my previous impression, the local server DOES correctly log all the artifacts in a local directory. We could change this directory to a common location (e.g. project diskspace) for running on SPICE, as an initial step before setting up a sql server etc.
