Exception raised when running examples

[jpxrc]

Hi,
I've properly formatted my .json files according to the style on the github page but am unable to run the pymot.py file. Even when I try running it on the groundtruth.json and hypotheses.json files included in the download, I still get the following error:

raise Exception, "Ground truth is not of class "video""

I get the same error even if I type the following into the terminal:

python pymot.py -h

Any ideas what's going on?

Please disregard the previous comment. The issue I ran into is a syntax error because I was running the script using Python 3 and the script assumes Python 2. The script seems to be working now.
