POMDP Planning Fails

[Jarvis-K]

Hi, I am running the training script. However, the ego car just keep still and the pomdp planner seems not working.

s = rospy.Service('adding_value', ValueService, lambda msg: handle_value(msg, socket))
print_flush("[attention_planner_training.py] episode successfully ended")
pomdp_proc.wait(timeout=int(config.eps_length / config.time_scale))
print_flush("[attention_planner_training.py] episode successfully ended")

The second print never comes out.

I have tried adapting the ego vehicle to use the gamma setting and doing so appears to resolve the issue. However, I would like to find a more permanent and reliable solution for the problem. Does anyone have any suggestions for what might be causing this issue and how it might be resolved?
Thank you for your time, and I look forward to your response.
