Question

当我尝试将经过gpu训练的模型加载到cpu时，这是一段代码：

model_conv.load_state_dict(torch.load(model_file, map_location='cpu'))
model_conv = model_conv.cpu()

，错误消息是：

Traceback (most recent call last):
  File "prediction.py", line 269, in <module>
    model_conv.load_state_dict(torch.load(resume_file, map_location='cpu'))
  File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/torch/serialization.py", line 229, in load
    return _load(f, map_location, pickle_module)
  File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/torch/serialization.py", line 377, in _load
    result = unpickler.load()
  File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/torch/serialization.py", line 348, in persistent_load
    data_type(size), location)
  File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/torch/serialization.py", line 246, in restore_location
    result = map_location(storage, location)
TypeError: 'str' object is not callable

我的pytorch版本是0.1.12_1。任何想法如何解决这个问题？我已经检查过how to load the gpu trained model into the cpu?，但该解决方案似乎不适用于我的情况。

任何建议都值得赞赏！

-更新- 如果不使用map_location参数，则错误消息为

Traceback (most recent call last):

    model_conv.load_state_dict(torch.load(resume_file))
