Working with Isaac Sim does not work well

[SnowMasaya]

I walked through the following link instruction

• https://github.com/NVIDIA-ISAAC-ROS/isaac_ros_visual_slam#working-with-isaac-sim

But it does not work well

ros2 launch isaac_ros_visual_slam isaac_ros_visual_slam_isaac_sim.launch.py

The following error happened. And I did not confirm the ros message.

[INFO] [launch]: All log files can be found below /home/admin/.ros/log/2022-04-30-04-43-54-457934-omn-a40-ubuntu-2718564

Could you tell me how to solve this problem?

Which platform? Are you running within the isaac_ros_common container or natively? Do you know which version of the CUDA toolkit you have installed? Any information about how you’re running it may help clarify the problem.

The information is followings

• isaac_ros_common container
• OS: Ubuntu 20.04
• NVIDIA driver: 470.82.01
• cuda: 11.4

Could you please try again with the latest Isaac ROS Visual SLAM and Isaac ROS Common?

[romi2002]

Hey, I'm having the same issue, with the latest ROS Visual SLAM and Issac ROS Common releases. Are there any steps I could take to debug this issue?

with:
* issac_ros_common container
* OS: Ubuntu 20.04
* Cuda 11.7
* Nvidia driver: 515.65.01

@romi2002 @hemalshahNV I have similar issue. component-container: process has died. Also Galactic version get this error too.

[hemalshahNV]

@romi2002 Could you tell us what GPU you're running (the output of nvidia-smi would be helpful)? Which versions of Isaac Sim are you running? Isaac Sim 2022.1.1 and Isaac ROS DP1.1 v0.11.0 should work well together.

[romi2002]

nvidia-smi returns the following,

Where can I check the Issac Sim version? I'm following the steps in the readme, running the sim inside docker with:

cd ~/workspaces/isaac_ros-dev/src/isaac_ros_common && \
  ./scripts/run_dev.sh

[hemalshahNV]

You'll want to run Isaac Sim on the host (not inside the Docker container).
