bitsauce / Carla-ppo

This repository hosts a customized PPO based agent for Carla. The goal of this project is to make it easier to interact with and experiment in Carla with reinforcement learning based agents -- this, by wrapping Carla in a gym like environment that can handle custom reward functions, custom debug output, etc.

self.world.wait_for_tick(seconds=1.0/self.fps + 0.1) gets struck forever. #6

Open pranavAL opened 5 years ago

pranavAL commented 5 years ago

In the env reset ticks never increase more than zero and the loop runs forever without moving forward. Seems the wait_for _tick id not at all receiving any input back from the server I wonder why?

hello, do you know how to run the make package command in the root directory of CARLA and add the town07 to the make package?

Sorry but I have been using only Town01 and Town02.

Hi Pranav,

Someone else mentioned this to me in an email, and I think it is strange that I didn't encounter this myself.

What I suggested is that maybe the simulation is taking longer than expected, and self.world.wait_for_tick will, therefore, time out repeatedly.

Have you tried to increase the seconds parameter (lets say, add 10 instead of 0.1) or replacing the self.world.tick() in the try-except block with a pass statement?

If it is caused by a timeout due to the seconds parameter, then that is an oversight on my part.

Good luck!

Hi Marcus,

I contacted one of the developers of CARLA and they suggested me that in the latest release you need not use world.wait_for_tick the same thing is done by world.tick and if used world.wait_for_tick after world.tick it always be struck in a deadlock situation. I am using 0.9.6 and your repo is based on 0.9.5 which might be making a huge difference.

Thanking You

Pranav Agarwal

@Pranav, How do you solve this problem？
