ValueError:X has 22032 features per sample;expecting 38916

[Tomingz]

I train my own data on windows,python3.6 , 192 pos images(RGB) and 192 neg images(RGB), size=(192,384)
[hog]
min_wdw_sz: [150, 300]
step_size: [8, 8]
orientations: 9
pixels_per_cell: [8, 8]
cells_per_block: [2, 2]
visualize: False
transform_sqrt:True
[nms]
threshold: 0.3
how to fix it?

You may resize the image to keep the length of feature vector consistent before you extract the HOG features. e.g. add a line 'im = cv2.imresize(im, (150, 300))' after #38 and #48 respectively. Also, add 'import cv2' in the beginning.
