Traceback (most recent call last):
File "convert.py", line 172, in
yolo4_model = Yolo4(score, iou, anchors_path, classes_path, model_path, weights_path, gpus)

File "convert.py", line 157, in init
self.load_yolo()

File "convert.py", line 142, in load_yolo
self.yolo4_model = multi_gpu_model(self.yolo4_model, gpus=self.gpu_num)

NameError: name 'multi_gpu_model' is not defined
