Python numpy reshape

Question

I have a variable of z storing features of length and height of image files where z is z = [length, height] and i want to change these dimension to just: z = [area] where area = length * height I tried using the numpy reshape function as follow: area = z.shape[0] * z.shape[1] #length * height z = z.reshape(-1) #was trying to reduce to just z = [area] but it seemed like I'm not using the reshape function correctly. Could anyone help me out?

Simple example of how to use reshape: import numpy as np a = np.random.randint(0,10,(10,10)) b = np.reshape(a, (100,)) print(b) For your case it will be: print(a.shape) # prints (length,height) b = np.reshape(a, (length * height,)) print(b.shape) # prints (length * height,) To perform a reshape in place you can also use: a.shape = ((100,))
