I am still getting this error, help me out.
You have to build the darknet_ros repo again.
Use:
catkin build darknet_ros
also source the file again.
chmod +x ~/catkin_ws/src/darknet_ros is not enough to make the ROS node file executable.
You have to locate the source file of the node, which probably is darknet_ros/ros/ yolo_object_detector_node.cpp, and make this file executable.

I posted about this over on the Isaac forums, but listing it here for visibility as well. I am trying to get the Isaac Realsense examples working on a Jetson Nano with my 435i (firmware downgraded to 5.11.15 per the Isaac documentation), but I've been unable to so far. I've got a Nano flashed with Jetpack4.3 and have installed all dependencies on both the desktop and the Nano. The realsense-viewer works fine, so I know the camera is functioning properly and is being detected by the Nano. However, when I run ./apps/samples/realsense_camera/realsense_camera it throws an error:
ERROR engine/alice/components/Codelet.cpp#229: Component 'camera/realsense' of type 'isaac::RealsenseCamera' reported FAILURE:
No device connected, please connect a RealSense device
ERROR engine/alice/backend/event_manager.cpp#42: Stopping node 'camera' because it reached status 'FAILURE'
I've attached the log of this output as well. I get the same error running locally on my desktop, but that's running through WSL so I was willing to write that off. Any suggestions would be greatly appreciated!

I have been trying to use use neo4j community in a container and am getting errors. I think this might more a docker usage issues rather than neo4j usage.
I have built a container image from https://github.com/neo4j/docker-neo4j-publish 2.3.9, 3.3.3, 3.3.4 and 3.3.5 (only differences being some new ports in later versions). I have even pulled a native 3.3.3 from dockerhub.com
mkdir /tmp/data
chmod 777 /tmp/data
docker run --detach=true --name=neo4j --publish=7474:7474 --publish=7687:7687 --publish=7473:7473 --volume=/tmp/data:/data neo4j:3.3.3
docker exec -it neo4j find / -name '*.log'
and although it seems to be working with

neo4j> CREATE (m),(o);

I actually get errors like this:
docker exec -it neo4j neo4j status
Neo4j is not running
Now this one looks like I am mistakenly trying to start another instance of Neo4j over a running instance:
docker exec -it neo4j neo4j console

Does anybody have experience with Neo4j's docker implementation? Is it a single threaded issue meaning I need to call the CLI tools differently from the container?
The neo4j status command only works if you've started neo4j with neo4j start. Start creates a neo4j.pid file that status uses to see if neo4j is running. Starting under docker uses the console option instead of the start option. This does not create the PID file, so the status doesn't work. But that hardly matters, because neo4j is just about the only process running; if neo4j dies, the container will exit. If docker ps -a says that the container is up, then neo4j is up.
I struggling to get the "Musicbrainz" data set running on my local machine (MacBook Air, Mountain Lion).
What I did? (Basically what the video said)
Downloaded data set directly from http://www.neo4j.org/develop/example_data
Downloaded fresh Neo4j-Community-2.1.5
Extracted the data set, renamed it to graph.db and copied to /neo4j-community-2.1.5/data/graph.db
Run the server: ./bin/neo4j console, but neo does not start - not even an exception is thrown!!!!
