加载预训练参数时，明明已经使用了strict=false，可还是报错，显示加载的参数维度不对
RuntimeError: Error(s) in loading state_dict for InceptionResnetV1:
size mismatch for logits.weight: copying a param with shape torch.Size([8631, 512]) from checkpoint, the shape in current model is torch.Size([340, 512]).
size mismatch for logits.bias: copying a param with shape torch.Size([8631]) from checkpoint, the shape in current model is torch.Size([340])
解决：当预训练参数的key和你改了维度的后的key相同时，参数会被强制加载进来，这种错误往往是因为修改num_classes，遇到这种问题解决办法是：：把修改维度的层名字换一个就行！
