TypeError: a bytes-like object is required, not 'str'

[ronger-git]

when i run convert.py in deep_sort_yolov4 ，it occurs TypeError: a bytes-like object is required, not 'str'.
is that a version error？

同样出现TypeError: a bytes-like object is required, not 'str'问题，代码定位在"convert.py" line 144, in load_yolo self.yolo4_model.save(self.model_path)，请问这个问题怎么解决呢？
