现在又有一个新的问题,如下:
Using` cuda device training.
Using 0 dataloader workers
Traceback (most recent call last):

博主您好,我在用MobileNetv2作为backbone训练Faster RCNN之后,进行Validation时,加载训练好的mobile-model-24.pth会报错。 Traceback (most recent call last): File "validation.py", line 215, in

但是我用res50fpn作为backbone训练Faster RCNN之后,Validation的时候加载训练好的res50fpn.pth就没错。
