Why Numpy's int datatype is not of the same type as Numpy's int64 datatype?

Question

Why does this give me false?

isinstance(np.int32(3.0),np.int)

As the docs say, int is platform dependent while int32 is guaranteed to be 32 bits long. — Michael Butscher, Mar 02 '20 at 12:29

Because np.int is the same as python int data type.

>>> np.int
<class 'int'>

To check with numpy.int32, you can try with np.int_,

>>> isinstance(np.int32(3.0),np.int_)
True
