I've got a total of around 7000 images from which I'm extracted HoG features. I then want to convert the list into an np array for further processing. But I get a memory error during the convertion.
Here's the relevant part of my code:
from skimage import data, io, filter, color, exposure
from skimage.feature import hog
from skimage.transform import resize
import matplotlib.pyplot as plt
import numpy as np
tmp_hogs = [] # this is the list I need to convert into a numpy array
for group in samplegroups:
for myimg in group:
curr_img = np.array(myimg, dtype=float)
imgs.append(curr_img)
fd, hog_image = hog(curr_img, orientations=8, pixels_per_cell=(4, 4),
cells_per_block=(1, 1), visualise=True, normalise=True)
tmp_hogs.append(fd)
img_hogs = np.array(tmp_hogs, dtype =float)
The error I get is:
Exception in thread Thread-1:
Traceback (most recent call last):

MemoryError
How can I fix it?
