np.bool depreciated

[sjentoft]

Function nipalsPCA is throwing an attribute error "module 'numpy' has no attirbute 'bool'. This is caused by using dtype=np.bool in cross_val.py. I suggest changing to bool as np.bool was depreciated in numpy version 1.20.

Thank you @sjentoft! Could you copy and paste the full error message here in this thread? Many thanks in advance.

It relates to this:

File xxxxx/cross_val.py:76, in LeaveOneOut.iter(self)
74 n = self.n
75 for i in range(n):
---> 76 test_index = np.zeros(n, dtype=np.bool)
77 test_index[i] = True
78 train_index = np.logical_not(test_index)

AttributeError: module 'numpy' has no attribute 'bool'.
np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
