loading a 3D array from a bin file - Mark3232 - May-04-2018

Hello Python forum

I am trying to load a 3D array from a bin file. However, when I load it is displayed as a long vector instead. 

data=np.fromfile("turbine32x32x8192.bin",dtype=float, sep='')
data.shape
>> (4194304,)
where it should have the shape 
data.shape
(32,32,8192)
What I am doing wrong ?

Thank you for reading!

Hello again Python Forum
I figured out a solution to the problem (Or rather I got help from an instructor) 

import numpy as np
data=np.fromfile("turbine32x32x8192.bin",dtype=np.float32, sep='')
then the array becomes 
Output:
data.shape 
>>(8388608,0)
Finally I can reshape the file the my desired array 
data=data.reshape(32,32,8192)
Output:
data.shape
>>(32,32,8192)
