turtlebot3_world yaml

[NildaX]

Can you show us the file "openai_ros/src/openai_ros/task_envs/turtlebot3/config/turtlebot3_world.yaml"? i have a problem with the network "ValueError: Input 0 of layer "sequential" is incompatible with the layer: expected shape=(None, 54), found shape=(None, 7)" in the file start_dqlearn_training.py.

Hi, I don't have the exact file on my local machine but I believe this is the same file ( https://github.com/zerosansan/td3_ddpg_sac_dqn_qlearning_sarsa_mobile_robot_navigation/blob/master/turtlebot3_rl_sim/src/configs/turtlebot3_world.yaml ). Concerning your error, try changing Line 93 of start_dqlearn_training.py to:

network_inputs = 7

In my implementation, I used 54 because I feed in 52 Laserscan distance inputs and 2 goal information inputs (heading to goal and distance to goal). You could try my new repository ( https://github.com/zerosansan/td3_ddpg_sac_dqn_qlearning_sarsa_mobile_robot_navigation) which removes openai_ros dependencies. So, it should be easier to get it running, the DQN implementation here is the same as my other repository. There are six RL algorithms, including Q-learning, SARSA, DQN, TD3, DDPG, and SAC.
