Error when running yelp/train.py about arae HOT 9 OPEN

@vineetjohn Good point! I used PyTorch 0.3.1. I'm adding this to the README

from arae.

Hmm, could you try maybe run with python3?

from arae.

I've run into the same issue.
Python 3.5.2
torch==0.4.1

Training...

Python3 clearly isn't the fix. It seems like something about the PyTorch + ONNX interop is broken.
Is there a specific version of PyTorch that's needed to run this?

You can try using my forked version of the repository to see if it fixes the issue for you.
I've verified it to be working for Python 3.5.2 and PyTorch 0.4.1
https://github.com/vineetjohn/arae

I've not identified the actual problem yet, but I've added a workaround that avoids having to deal with ONNX altogether. The pack_padded_sequence method in torch.nn.utils.rnn seems to be buggy.

Guys can you try python 3.6? @jiwoongim @vineetjohn

@jiwoongim
You can try using my forked version of the repository, I have resolved the issue by doing several changes to the original code.
I have verified it to be working for python 3.6.5 and PyTorch 0.4.1

@jakezhaojb

This doesn't look like a Python version issue.
The named arguments used in this project vs. those accepted by PyTorch 0.4.1 are inconsistent.

You should consider adding the version of PyTorch used to perform your experiments, to the project README.

I have run your forked version in python 3.6.5 with PyTorch 0.4.1 (Cudnn=7.1.3, Cudatoolkit=8.0) and I have a error as follow:

Can you give me some advices?

@dangvanthin Hi, I met the same problem. Do you have the solution right now? Thank you
