Syntax error in extract_features_from_prevectors.py

[Ropena]

When running the python script extract_features_from_prevectors.py it throws a syntax error in line 7:

line 7: syntax error near unexpected token (' line 7: with open ("prevectors.json", "r") as f:'

It also prints out: "from: too many arguments"

I'VE LOOKED AT THE CODE BUT COULD NOT FIND ANYTHING WRONG. ANY IDEAS?

First thought, py2 or py3? This was originally written for Python 2.7.
