What is the difference between resize and reshape when using arrays in NumPy?

Question

I have just started using NumPy. What is the difference between resize and reshape for arrays?

Answer 1

One more point is:

np.reshape can take -1 in one dimension. np.resize can't.

Example as below:

arr = np.arange(20)
arr.resize(5, 2, 2)
arr.reshape(2, 2, -1)
