Hi Qing, Thanks for picking this issue. How would multiple inputs/labels be handled? By name or by position?
Background: Recently I faced issue in Python where name of the input symbol name was not used, but, position was used. Python2 reads list from 0 and Python3 reads list from last element. So based on the python version, I was having swapped symbol and hence shape mis match errors.
