How to convert a (10000, 10, 10) array to (10000, 100, 1) in python?

Question

I am getting IndexError if I try doing it using a for loop.

Any good way to go about it?

Try `np.reshape()`. This is duplicate to https://stackoverflow.com/questions/30668223/how-to-change-array-shapes-in-in-numpy — Mr_U4913, Oct 11 '19 at 20:38

Use the reshape() method on the array. (It's also avilable as a NumPy function, np.reshape().)

Try this:

import numpy as np
arr = np.random.random((10000, 10, 10))
arr.reshape((10000, 100, 1))

In general, you almost never need a loop with NumPy arrays.
