The numpy.zeros_like() method consists of four parameters, which are as follows: arrray : This parameter represents an array_like input subok :It true is invoked then it represents newly created array will be sub-class of array else it represents a base-class array order :The order parameter can be either C_contiguous or F_contiguous. Fill value. Pylint gives a false-positive error while using numpy.zeros_like (). Equivalent to a.copy().fill(0). The shape and data-type of a define these same attributes of the returned array. type of ‘a’, otherwise it will be a base-class array. Use numpy.zeros() outside the call to this function to create the output array, and it should work (not sure if shape support handles indexing that well, however). import numpy as np; use np.zero_like to Initialize a ndarray like dW = np.zeros_like(W) 3.write dW[1,:] or any dW related code above except dW = np.zeros_like(W) Logs.
