Download Meteor Data File Before Running Eval

[YuanSamuel]

What it Does

The METEOR evaluation was broken due to needing the data/paraphrase-en.gz file.

• Added script to download the file before evaluation.
• Improved logging in meteor.py file
  • Debugging this error was hard because all the script would return was a BrokenPipeError: [Errno 32] Broken pipe error that pointed to the wrong line
