2 years ago Solved, when generate pre-rendered alpha maps for stroke, crop_alpha_area(alpha) returns some one-dimensional vectors, and the judgment statement only determines whether it is empty or not. When the return is a one-dimensional vector, it will cause cv2.resize to report an error. The following code should be added to util_lib/gen_pams.py line 95
if alpha_crop.shape[1]==0: continue if alpha_crop.shape[0]==0: continue
