AttributeError: 'str' object has no attribute 'decode'

@luvWY Hello, I have some problems running the yolo_video.py program. The problem is as follows: Traceback (most recent call last): File "yolo_video.py", line 106, in detect_video(YOLO(**vars(FLAGS)), FLAGS.input, FLAGS.output) File "C:\Users\GenkiTek\Desktop\people_count_keras\people_count_keras\people_count_keras\keras-yolo3\yolo.py", line 90, in init self.boxes, self.scores, self.classes = self.generate() File "C:\Users\GenkiTek\Desktop\people_count_keras\people_count_keras\people_count_keras\keras-yolo3\yolo.py", line 123, in generate self.yolo_model.load_weights(self.model_path) # make sure model, anchors and classes match File "C:\Users\GenkiTek\anaconda3\envs\py37\lib\site-packages\keras\engine\saving.py", line 492, in load_wrapper return load_function(*args, **kwargs) File "C:\Users\GenkiTek\anaconda3\envs\py37\lib\site-packages\keras\engine\network.py", line 1230, in load_weights f, self.layers, reshape=reshape) File "C:\Users\GenkiTek\anaconda3\envs\py37\lib\site-packages\keras\engine\saving.py", line 1183, in load_weights_from_hdf5_group original_keras_version = f.attrs['keras_version'].decode('utf8') AttributeError: 'str' object has no attribute 'decode' what is the problem
