pytorch训练网络：双卡训练，单卡测试报错问题

Missing key(s) in state_dict:
Unexpected key(s) in state_dict

---

1.报错

报错如下（示例）：

RuntimeError: Error(s) in loading state_dict for ***:
        Missing key(s) in state_dict: "feature_color.0.weight", "feature_color.0.bias", "feature_color.1.weight", . 
        Unexpected key(s) in state_dict: "module.feature_color.0.weight", "module.feature_color.0.bias". 

解决方案

torch.load(path)
weights_dict = {} 
for k, v in ckpt['***'].items():

    new_k = k.replace('module.', '') if 'module' in k else k
    weights_dict[new_k] = v

decoder_net.load_state_dict(weights_dict)

总结
