Summary:
There is a module called `2to3` which you can target for future specifically to remove these, the directory of `caffe2` has the most redundant imports:
```2to3 -f future -w caffe2```

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18560
We have to import python protobuf here **before** we load cpp extension.
Otherwise it breaks under certain build conditions if cpp implementation of
protobuf is used. Presumably there's some registry in protobuf library and
python side has to initialize the dictionary first, before static
initialization in python extension does so. Otherwise, duplicated protobuf
descriptors will be created and it can lead to obscure errors like
Parameter to MergeFrom() must be instance of same class: expected caffe2.NetDef got caffe2.NetDef.
I think it also fixes https://github.com/facebookarchive/caffe2/issues/1573
