bug in updated Tracking.py (?)

[annesophiefortin]

I have updated my py-eddy-tracker to have all the new examples (thank you a lot for that, it is very useful).
But now, when I run python Tracking.py tracking.yaml, I get the following error message:

YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  config = yaml_load(stream)
Traceback (most recent call last):

Here is my tracking.yaml file:
