report error
AttributeError: ‘collections.OrderedDict‘ object has no attribute ‘eval‘
reason
The reason for this error is that the class object of your collecttions does not have the eval attribute.
Most of the reason is because the following statement is used to save the model.
torch.save(model.state_dict(),model_path)
But in fact it is not a model file, but a parameter file. In the model file, the complete model is stored, while in the state file, only the parameters are stored. So collections.OrderedDict is just the value of the model.
solution
Apply the following statement to save the model
#保存时
torch.save(model,'save_path')
#加载时
torch.load('save_path/model')
