How do read .npy files in matlab?
显示 更早的评论
Hello.
In matlab it is possible to read the extension .npy, or in its absence the extension .LVM of Labview.

I copied readNPY.m and readNPYheader.m from there and could then easily read npy-images into matlab.
Thankyou very much! /Maria

Is it possible for you to show or briefly explain how to use this readNPY.m and readNPYheader.m/how to integrate this to our codes?

If you have access to Python, the easiest thing would be to create a Python script such as the one below, and run that. It will find all .npz files in the current directory and convert that to .mat.
from scipy.io import savemat
import numpy as np
import glob
import os
npzFiles = glob.glob("*.npz")
for f in npzFiles:
fm = os.path.splitext(f)[0]+'.mat'
d = np.load(f)
savemat(fm, d)
print('generated ', fm, 'from', f)

i tried this, it seems to work but it's asking me to allow_pickle=True

In my case I had to do something like this
X = np.load('./dataset/dataset_Xs.npy')
savemat('./dataset/dataset_Xs.mat', {'X': X})

Yes, use code like this.
x = py.numpy.load('data.npy')

No. That'd be how to do it with python, not in MATLAB.

Hi Mike,
Did you try it? This works for me. Note that "py." is prepended to the normal Python command "numpy.load('data.npy')".
>> x=py.numpy.load('data.npy')
x =
Python ndarray:
1 2 3
4 5 6
7 8 9

No, that is how to do it from MATLAB, not from Python:

Hello Juan,
I don't believe that either of those file formats are natively supported in MATLAB, but you can always check File Exchange to see if anyone has written an importer for them. A quick search did not turn up anything for NPY, but LVM turned up this one. If you have any questions about that File Exchange package, it's best to direct them to the author of the package.

One more reason to stop using Matlab. Python indeed has libraries to make use Matlab.

MATLAB indeed has functions to make use Python:
