Run AlphaPose for all images：TypeError: only integer tensors of a single element can be converted to an index

[yulin011]

reason：invalid parameter in cv2.ellipse2Poly() in fn.py
raw code:

line 214 in fn.py : polygon = cv2.ellipse2Poly((int(mX),int(mY)), (int(length/2), stickwidth), int(angle), 0, 360, 1)

stickwidth is a float tensor which is not suitable for param.axes in cv2.ellipse2Poly(), so l tried to turn "stickwidth" to "int (stickwidth)",
thus promising code running. but this may affect the pattern of skeleton
