I think it is because the ATen does not support std=c99 in 0.4.1. By the way, the cc_attention does not support 1.0.0 too while the latter does not support torch.utils.ffi.

acgtyrant commented 5 years ago

The easist solution is fix the wrong doc "To install PyTorch>=0.4.0" in README.

speedinghzl commented 5 years ago

@acgtyrant Thanks for your attention. This repo indeed does not support torch 1.0. And you can modify the std=c99 into std=c++11 to support torch 0.4.1. In fact, this repo does use the newest feature for c++ interface, e.g. ATen, runtime-compile due to the low version gcc (4.8.5) in our cluster. The doc is updated.
