How to access the goal_state from database using python interface ?

[chandarr]

in the heatmap_generator.py, the goal (positions) is accessed using r.goal()[0:3,3].

The other values of score and reachable are accessible using r.score and r.reachable.

We want to use the goal_state values for each of the goals to perform certain analysis.

Trying to use r.goal_state() generates a "no python class registered" error.

How would you recommend to access the goal_state values ?

Thanks
