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.

The linux and macOS runs have only a few failing tests:

FAILED sparse/tests/test_construct.py::TestConstructUtils::test_bmat - Assert...
FAILED stats/tests/test_sampling.py::TestTransformedDensityRejection::test_bad_pdf[<lambda>-TypeError-must be real number, not list]
FAILED stats/tests/test_sampling.py::TestTransformedDensityRejection::test_bad_dpdf[<lambda>-TypeError-must be real number, not list]
FAILED stats/tests/test_sampling.py::TestNumericalInversePolynomial::test_bad_pdf[<lambda>-TypeError-must be real number, not list]

The first seems to be an error in printing a dict:

AssertionError: Regex pattern \
    'Mismatching dimensions along axis 1: {1, 2}' does not match 
    'Mismatching dimensions along axis 1: {2, 1}'.

The last 3 are from TransformedDensityRejection.__cinit__:

AssertionError: Regex pattern \
    'must be real number, not list' does not match 
    "unsupported operand type for float(): 'list'".

The windows one hits https://github.com/scipy/scipy/issues/15121

At least the hangs in TestNQuad::test_fixed_limits seem to be gone 💪

On the other hand, given the wrong number of failures in the student distribution (not exactly a rarely used function), I think we cannot progress on this unless we fix that issue (or skip win+pypy).

given the wrong number of failures in the student distribution

If this was about studentized_range, that is different (and less common) than Student's t distribution, but I know that at least two other packages (pingouin and statsmodels) now rely on it for Tukey's HSD test (and we do, too).

This may be a JIT bug in register allocation on windows, see PyPy issue 3753
