Existing container not stopped

Warning

The AI Accelerator requires ROS 2 Humble, so PolyScope X 10.12.1 is the latest compatible release. PolyScope X 10.13 and later use ROS 2 Jazzy and are not currently supported.

Symptoms

An example fails or behaves oddly while another example is already running in a different terminal.

Cause

Only one Isaac SDK session (isaac_pkgs_app) should own the GPU / example stack at a time.

Fix

On the host (not inside the container):

docker ps

A healthy setup looks similar to:

Example docker ps output showing AIA and Isaac containers

Name (partial)

Role

camera-node-urcap-backend

Camera URCap backend

aia-core-backend

AIA Core (often port 35000)

aia-calib-backend

Calibration backend

isaac_pkgs_app

SDK container (run_sdk_setup.sh / examples)

All should show STATUS Up .... For a clean example restart:

docker stop isaac_pkgs_app

Then start the example again from a fresh ./scripts/run_sdk_setup.sh session.
