How do you open .NPY files?

Question

How do I open .NPY files in python so that I can read them? I've been trying to run some code I've found but it outputs in .NPY files so I can't tell if its working.

Answer 1

*.npy files are binary files to store numpy arrays. They are created with

import numpy as np

data = np.random.normal(0, 1, 100)
np.save('data.npy', data)

And read in like

import numpy as np
data = np.load('data.npy')
