@liudaxia96 - could you provide a description of the bug and steps to reproduce it?

Training started at epoch 0 until 720. One training epoch = 18 iters. One eval epoch = 7 iters. Could not import cythonized box intersection. Consider compiling box_intersection.pyx for faster training.

Can you try this with Python 3.6? It seems to be a pickling error in Python 3.8
