How to convert 4 dimensional array into 2 dimensions and save as csv in python

Question

I have a 4 dimensional array with shape (1, 2000, 102, 32)

I would like to convert it to (64000,102) 64000 is based on (2000*32).

Then store it in csv file.

Thanks

Does ordering of the dimensions matter? If not, you can just use numpy reshape function. Example is below.

import numpy as np
a=np.zeros((1, 2000, 102, 32))
print(a.shape)
b=a.reshape(64000,102) 
print(b.shape)

Hi, This didn't work out. Cause the shape of the array is 4 dimension and the dimensions are (1,2000,102,32). I want to reduce the dimensions to 2D (64000, 102)

Quick question, does this reshape place the first 2000 rows and then append next 2000 rows in a sequence?

Yes. It just flattens everything and follows the normal sequence.
