Fix python library versions for devops and review notebook pictures

[jmservera]

Hi, I've fixed some paths in the notebook pictures that didn't show, fixed the python library versions because the score.py was failing, and had to change a few code lines. We should also renew some libraries but it will take more work. I've also changed the way we check for changes, because it was only checking for the model version, but it is possible to have to change the score.py, so when the model does not change it is not registered but the docker file and the ACI is still created.
