🐛 Bug

The changes in commit d26e112 to move away from the deprecated torch type at::DeprecatedTypeProperties seems to have broken the build: https://travis-ci.org/pytorch/audio/builds/578519920

                 from torchaudio/torch_sox.cpp:1:
torchaudio/torch_sox.cpp: In lambda function:
torchaudio/torch_sox.cpp:40:42: error: expected primary-expression before ���>’ token
     auto* data = tensor.data_ptr<scalar_t>();
                                          ^
/home/travis/miniconda3/envs/testenv/lib/python3.7/site-packages/torch/include/ATen/Dispatch.h:12:12: note: in definition of macro ‘AT_PRIVATE_CASE_TYPE’
     return __VA_ARGS__();                          \
            ^

                                            ^

Environment

• What commands did you used to install torchaudio (conda/pip/build from source)?

Fails on travis and when building/installing with:

pip install git+git://github.com/pytorch/audio.git
