need to edit opencv_transform/maskdet_to_maskfin.py line 168

vim /Users/Aiker/Desktop/deepnude/deepnude/opencv_transform/maskdet_to_maskfin.py +168

_, contours, hierarchy = cv2.findContours(color_mask,cv2.RETR_TREE      ,cv2.CHAIN_APPROX_SIMPLE)

then it's OK.

THX,but why?

There are not enough variables to unpack. two vars,but there are three values behind.
