Is it known that the provided file parser (from https://github.com/GOCompetition/Evaluation/blob/master/data.py ) fails on the provided 14 bus dataset .RAW file? Removing the slash and comment text from the end of the first line of 'case.raw' fixes this.
The 14 bus dataset .RAW has not been checked for compliance recently; the focus has been on the competition datasets. This will be fixed eventually, but is not a priority for now.
