How to get the true dimension of a numpy array in python?

Question

I try to display a numpy file, then display its correct length, I put my file in folder:

import numpy as np
import os
path= "C:\\Users\\user\\Folder"
files= os.listdir(path)
filepath= os.path.join(path, files[0])
file0= np.load(filepath)
print(file0)
print (len(file0))

The result is an imbrication of tables, which gives me as length=1 instead of length=8000 :

[[ 0.01437869 0.01506449 0.01579909 ..., 0.04166172 0.0417285
 0.04172079]]
1

But I need to have is:

[ 0.01437869 0.01506449 0.01579909 ..., 0.04166172 0.0417285
 0.04172079]
8000

How to resolve this problem please.

• Divakar: Use .ravel() or np.squeeze().
• Nils Werner: and have a look at .shape instead of len().
• hpaulj: Looks like the true file0.shape is (1,8000).

Answer 1

This should work:

file0= np.load(filepath)[0]

• Jaime: I like this syntax to unpack single item sequences better, but YMMV: file0, = np.load(filepath).
