A negative value appears in the Python numpy sum ()

Import NumPy

A=numpy.random.randint (1, 4095, (5000,5000))

A.sum ()

The result is negative, which is wrong, the type of A.sum () is Int32, how can the result be displayed correctly? Follow this procedure:

c=Numpy.int64 (a). SUM ()

The result is upright, correct, and C is of type Int64. The cause is the following, and the result is the same type as the element.

If D=numpy.int64 (A.sum ()) is not working, the result is negative.

Other people will not have this situation, some will appear, the reason is not very clear.

Python comes with view type method type (d)

NumPy, the type is attribute, so d.dtype
