TypeError: attempt_load() got an unexpected keyword argument 'map_location'

报错原因

yolov5的版本做了升级了。attempt_load的参数做了调整。如下代码：

def attempt_load(weights, device=None, inplace=True, fuse=True):
    # Loads an ensemble of models weights=[a,b,c] or a single model weights=[a] or weights=a
    from models.yolo import Detect, Model

解决方法

将map_location改为device

 # Load model
 self.model = attempt_load(opt.weights, device=self.device)  # load FP32 model
