I try to run the BiLSTM Max-out trained model but I get the following error message

Traceback (most recent call last):

ImportError: torch.utils.ffi is deprecated. Please use cpp extensions instead.

which says that torch.utils.ffi is deprecated.

I recently had this problem too. Downgrading to pytorch 0.3.1 worked for me. I was using pytorch 1.0.0, and it seems to be a problem coming from pytorch: https://github.com/pytorch/pytorch/issues/15645
