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/recipe.yaml) and found it was in an excellent condition.

Looks like the CI pipelines are failing because the unittests are failing. The template being generated here aren't matching the set of fixed templates, giving different answers for certain numbers (11 vs 12). This is likely due to rounding differences.

The failures seem to be repeating in CI, so don't seem to be transient numerical precision issues. I cannot reproduce them on my machine. Do you have any recommendations on how to address the failures in the feedstock?

@duncanmmacleod I agree these don't look to be transient, the tests here are systematically rounding to a higher value (regardless of units like minutes vs hours vs months). This rounding is done by naturaldelta in the jinja-humanize extension, which falls under the python package humanize. I noticed that that versions in the latest job for this and the latest in the ligo-followup-advocate repo don't match, and we don't currently pin this version.

I can see a PR for humanize 4.15.0 that changed how naturaldelta works, switching from rounding via int() to round(): python-humanize/humanize#272

Here's a fix that updates this version and the templates for ligo-followup-advocate that you can backport: https://git.ligo.org/emfollow/ligo-followup-advocate/-/merge_requests/236
