RuntimeError: Error(s) in loading state_dict for DataParallel:

用pytorch搭建基于GPU运行环境的神经网络，训练时报错如下：

RuntimeError: Error(s) in loading state_dict for DataParallel:

    Missing key(s) in state_dict: "module.features.0.weight", "module.features.0.bias", "module.features.2.weight", "module.features.2.bias", "module.features.5.weight", "module.features.5.bias", "module.features.7.weight", "module.features.7.bias", "module.features.10.weight", "module.features.10.bias", "module.features.12.weight", "module.features.12.bias", "module.features.14.weight", "module.features.14.bias", "module.features.17.weight", "module.features.17.bias", "module.features.19.weight", "module.features.19.bias", "module.features.21.weight", "module.features.21.bias", "module.features.24.weight", "module.features.24.bias", "module.features.26.weight", "module.features.26.bias", "module.features.28.weight", "module.features.28.bias", "module.classifier.0.weight", "module.classifier.0.bias", "module.classifier.3.weight", "module.classifier.3.bias", "module.classifier.6.weight", "module.classifier.6.bias".

对治方法：
将
net = torch.nn.DataParallel(net)
删除即可。
