Subclassing numpy ndarray problem

Question

I would like to subclass numpy ndarray. However, I cannot change the array. Why self = ... does not change the array? Thanks.

import numpy as np         


        

Answer 1

I tried to do the same, but it is really very complex to subclass ndarray.

If you only have to add some functionality, I would suggest to create a class which stores the array as attribute.

class Data(object):

    def __init__(self, array):
        self.array = array

    def remove_some(self, t):
        //operate on self.array
        pass

d = Data(z)
print(d.array)
