AttributeError: module 'numpy' has no attribute 'int'.

[david-waterworth]

PyGam appears to require numpy < 1.20 i.e. the use of .astype(np.int) hasn't been supported for some time. I'm getting the error below with the latest numpy release that satisifies my other project constraints (and I cannot roll back to 1.20)

File pygam/utils.py:649, in b_spline_basis(x, edge_knots, n_splines, spline_order, sparse, periodic, verbose)
    646 aug_knots[-1] += 1e-9 # want last knot inclusive
    648 # prepare Haar Basis
--> 649 bases = (x >= aug_knots[:-1]).astype(np.int) * \\
    650         (x < aug_knots[1:]).astype(np.int)
    651 bases[-1] = bases[-2][::-1] # force symmetric bases at 0 and 1
    653 # do recursion from Hastie et al. vectorized

AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations"

First I used pygam = "*", and for some reason poetry had installed pygam version 0.8.0 for me. And I hit this same issue.

Fix: Specify the latest version pygam = "0.9.1" and it works with numpy 1.26.4.
