Any ideas what's wrong here? Is it a question of np.bool8 being deprecated in favour of np.bool_?

Apparently the package already uses both 🤔:

decohost /var/tmp/portage/dev-python/nptyping-2.5.0/work/nptyping-2.5.0 # rg np.bool
tests/test_mypy.py
121:            NDArray[Any, np.dtype[np.bool_]]

tests/test_ndarray.py
269:        self.assertIsInstance(np.array([True]), NDArray[Any, np.bool_])

nptyping/typing_.py
50:Bool = np.bool_
51:Bool8 = np.bool8

nptyping/typing_.pyi
49:Bool: TypeAlias = np.dtype[np.bool_]
50:Bool8: TypeAlias = np.dtype[np.bool8]

I just ran into a large list of warnings as well.

Appears to be a few deprecations in Numpy v1.24:

• Redundant aliases to built-in type aliases - np.str, np.int etc
• Old, unnecessary type aliases - np.str0, np.bool8

Is it a question of np.bool8 being deprecated in favour of np.bool_

From what I can gather, numpy's dtype needs something not built-in internally, so that's what np.bool_ is for. From a user's point of view, I think we're supposed to be just using bool.

Some enlightening code:

>>> import numpy as np
np>>> np.bool
<type 'bool'>
>>> np.bool is bool
True
>>> np.bool_ is bool
False 

>>> np.ones(2, dtype=bool).dtype
dtype('bool')
>>> np.ones(2, dtype=np.bool_).dtype
dtype('bool')
