Serialization method which is same with the one in torch7

I’m transferring my codes from torch7 to pytorch.
I used torch.serialize to convert arbitrary objects into strings and write them to a file.
Then I loaded the file and converted strings into objects.
But I could not find a function that does the same job in pytorch.

Is there any same method (torch.serialize/deserialize) in pytorch?

python has pickling for this.
