…y 2.5 hmmlearn 0.3.3's own hmm.py/utils.py assign a.shape in place, which numpy 2.5 deprecates; this project's pytest config promotes that DeprecationWarning to a hard error, failing nearly every test. Reproduces with numpy>=2.5 on any architecture, not just riscv64.
_hmmc has no Py_mod_gil slot, so cp314t re-enables the GIL at import and warns; hmmlearn's own filterwarnings=["error", ...] turns that into a collection error. -X gil=1 rather than PYTHON_GIL=1, since -I (already in the test command) ignores PYTHON* env vars.
