[vfdev-5]

Description:

• Fixed torch randint incoherent sampling (compatible to random.randint)

Code with random.randint:

• https://github.com/pytorch/vision/pull/2342/files#diff-549cc9d2872b8748db818d9a51e34708L508

i = random.randint(0, h - th)
j = random.randint(0, w - tw)

• https://github.com/pytorch/vision/pull/2386/files#diff-549cc9d2872b8748db818d9a51e34708L1410

i = random.randint(0, img_h - h)
j = random.randint(0, img_w - w)
