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.

Importing scikitlearn is failing to import joblib which is failing to import cloudpickle because PyPy has no _pickle accelerator module. A victim of this issue which seems to be due to cloudpickle depending on undefined pickle behaviour (even on CPython, when using the pure-python pickle module cloudpickle fails). This comment from a scikit-learn contributor suggests there is a fix for this in upstream? I couldn't find it searching issues and PRs in the repo, but maybe my search-foo is too weak.

[mattip]

The joblib failure is a bit strange since upstream both tests with pypy and vendors cloudpickle.

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

I was trying to look for recipes to lint for you, but it appears we have a merge conflict.
Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.
