predict_ros.py error finding model path

[ifeeney]

Hi,

I was trying to run predict_ros.py and noticed that it does not pass a model_path into the Tracker() constructor. Looking at past commits, I see you made a change to predict.py to default the model_path argument to none. I think that change may be causing this error when running predict_ros.py...

Thanks for bringing this up! Like you said, it is possible that the change for the predict.py did not take into account the predict_ros.py. First of all, did you successfully run the predict.py for the public datasets?

I was able to successfully run predict.py with the example data but ran into an issue when running predict_ros.py. I was able to narrow down the problem to that particular change.

Great to hear that you got success running the examples. For ros, you might need a bit modification, such as providing model_path which is the path to the CAD model (refer to the example)
