Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

We added this new dependency with MLflow 1.5.0 - it's only available on conda via an out-of-date / seemingly unmaintained channel (https://anaconda.org/giperball/prometheus-flask-exporter). As described in conda/conda-build#548, it's not currently possible to include PyPI-only dependencies in conda recipes, & there doesn't seem to have been progress on allowing recipes to depend on packages in custom conda channels (see conda/conda#1504), so will remove the prometheus-flask-exporter dependency for now.

[xhochy]

These dependencies are straight-forward to add: conda-forge/staged-recipes#10505 No need to remove them.

Ah thanks @xhochy! Now that it's on conda-forge, would be happy to approve a PR adding the prometheus-flask-exporter dependency to the MLflow recipe
