Describe the bug Fail to load the map to the RViz simulation

To Reproduce I just try to run cd ~<PATH_TO_FOLDER>/DRL-robot-navigation/TD3 python3 train_velodyne_td3.py follow the tutorial , but it seems there is some issues that it can not visulize and train as expected.

Expected behavior The trainning simulation appear normally with the world with obstacles.

Desktop (please complete the following information):

Additional context I have look into issues and comments on #16 but still i can not solve this problem. By the way, I have successfully lunch the TD3.world in gazebo following the suggestion on #16

Hi,

It seems like your resource path is not sourced properly. This will depend on where you have cloned the repo to. See the answers here: https://github.com/reiniscimurs/DRL-robot-navigation/issues/64

I have follow the instruction on the #44 and tutorial to identify the source of gazebo and check other resourcec path. It seems to have been set correctly by the command export ROS_HOSTNAME=localhost export ROS_MASTER_URI=http://localhost:11311 export ROS_PORT_SIM=11311 export GAZEBO_RESOURCE_PATH=~playground/DRL-robot-navigation/catkin_ws/src/multi_robot_scenario/launch source ~/.bashrc cd playground/DRL-robot-navigation/catkin_ws source devel_isolated/setup.bash I also have use echo $GAZEBO_RESOURCE_PATH to check GAZEBO path before and after it seems to be correct as specify in the tutorial. image

Seems to me you are missing a /

Try: GAZEBO_RESOURCE_PATH=~/playground/DRL-robot-navigation/catkin_ws/src/multi_robot_scenario/launch source

Thanks! With your advice, I've resolved the issue. Since, I am not that familiar with ubuntu and gazebo ros so my question seem tobe a little bored. But thanks again for your timely response,your responce really help me a lot.
