Arvados

The pip install documentation for arv-cluster-activity tells you to run pip install arvados-cluster-activity[prometheus], but that package doesn't even exist:

% py -m venv arv-cluster
% arv-cluster/bin/pip install 'arvados-cluster-activity[prometheus]'
ERROR: Could not find a version that satisfies the requirement arvados-cluster-activity[prometheus] (from versions: none)
ERROR: No matching distribution found for arvados-cluster-activity[prometheus]
% arv-cluster/bin/pip install 'arvados-cluster-activity'
ERROR: Could not find a version that satisfies the requirement arvados-cluster-activity (from versions: none)
ERROR: No matching distribution found for arvados-cluster-activity

As best I can tell from searching PyPI, this isn't just a typo, we just have not uploaded this package to PyPI at all.
