ValueError: zero-size array to reduction operation minimum which has no identity

Hello,

I met the title problem in step 2 make_target.py, the 1918 image. I think the reason is pytorch version. I use pytorch 1.0.0. In line 98&99 of make_target.py

img[int(head_cord[1] - crop_size): int(head_cord[1] + crop_size), int(head_cord[0] - crop_size): int(head_cord[0] + crop_size), :]

the start index might be negative when the person is on the edge of images. So I add a constraint on it :

head = img[max(0, int(head_cord[1] - crop_size)): int(head_cord[1] + crop_size), max(0, int(head_cord[0] - crop_size)): int(head_cord[0] + crop_size), :]

This would guarantee the index at least be 0.
