Topic Description

Detailed Description

I’m encountering an issue when trying to enable the ROS 2 Bridge extension in Isaac Sim 4.5.0. The extension fails to load with the error message “No [paths] found in omniverse.toml”, and it cannot be enabled.

Steps to Reproduce

  1. clone the repo: GitHub - isaac-sim/IsaacSim-ros_workspaces at e4d697019ccd2ec25f0607f2c4b17d3c418162e2 and checkout to the corresponding commit.
  2. cd IsaacSim-ros_workspaces
  3. sudo ./build_humble.sh:
  1. source and run Isaacsim:
  1. Isaac Sim Launched successfully
  1. But when I tried to enable the ROS 2 Bridge extension, it shows No [paths] found in omniverse.toml and the extension cannot be enabled.

Additional Information

I referred to the document below to set up the ROS2 bridge: ROS and ROS 2 Installation — Isaac Sim Documentation

What I’ve Tried

I installed Docker via:

sudo apt-get install -y ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o \
  /usr/share/keyrings/docker.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] \
  https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list
sudo apt-get update && sudo apt-get install -y docker-ce docker-ce-cli containerd.io
sudo usermod -aG docker $USER && newgrp docker
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/libnvidia-container/gpgkey | \
  sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit.gpg
curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
  sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit.gpg] https://#' | \
  sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
sudo apt-get update && sudo apt-get install -y nvidia-docker2
sudo systemctl restart docker

Any guidance on resolving this error would be appreciated!

Given that you’re using an older version (4.5.0) and a slightly older Ubuntu distribution (20.04), it might be beneficial to try Isaac Sim 5.0. This version often brings significant updates and bug fixes.
