Running mlconvgec2018 for inference ?

[yashkumaratri]

OS : Ubuntu 16.04
Python Version : 3.5
CUDA : 8

Whenever I setup farseq-py by running python3 setup.py install (The one which gets downloaded by download.sh script)
I get

cmd_obj.run()
File "setup.py", line 49, in run
  conv_tbc.build()
File "/home/ubuntu/.local/lib/python3.5/site-packages/torch/utils/ffi/__init__.py", line 184, in build
  _build_extension(ffi, cffi_wrapper_name, target_dir, verbose)
File "/home/ubuntu/.local/lib/python3.5/site-packages/torch/utils/ffi/__init__.py", line 108, in _build_extension
  outfile = ffi.compile(tmpdir=tmpdir, verbose=verbose, target=libname)
File "/home/ubuntu/.local/lib/python3.5/site-packages/cffi/api.py", line 697, in compile
  compiler_verbose=verbose, debug=debug, **kwds)

  outputfilename = _build(tmpdir, ext, compiler_verbose, debug)

  raise VerificationError('%s: %s' % (e.__class__.__name__, e))
cffi.error.VerificationError: CompileError: command 'x86_64-linux-gnu-gcc' failed with exit status 1

But as per issue#2 I used latest fairseq but now I am running in lot of conflict like

Now the question is how to use that ./run.sh -------------------------------------------------- to make it inference.

Tried the solution proposed by @renhongkai in #2 (comment)

But a new error popped up

So How to make your code to work ?

[shamilcm]

To make the scripts work and replicate exact results, you have to use the specified Fairseq commit in download.sh (which requires PyTorch 0.2.0post3 compiled from source).

The latest version of Fairseq has numerous changes.

For example, in the latest version of Fairseq, generate.py --interactive is replaced by a separate script interactive.py. Also, when you have to decode with multiple models, instead of giving them as

--path models/mlconv_embed//model1.pt --path models/mlconv_embed//model2.pt --path models/mlconv_embed//model3.pt --path models/mlconv_embed//model4.pt

you have to give:

--path models/mlconv_embed//model1.pt:models/mlconv_embed//model2.pt:models/mlconv_embed//model3.pt:models/mlconv_embed//model4.pt

If you are using the latest Fairseq, do not rely on the released shell scripts as they were written for an older version that is used in this work. You will have to follow the Fairseq documentation and use the released models alone. It may perhaps be better to retrain models using the latest version of Fairseq and test using the same.
