[setParam] Failed to contact master at [localhost:11311]. Retrying...

edit

I'm trying to run ros_deep_learning (https://github.com/dusty-nv/ros_deep_...) and do single image classification (https://giters.com/dusty-nv/ros_deep_...). I'm running:

roslaunch ros_deep_learning imagenet.ros1.launch input:=/home/USR/catkin_ws/src/ros_deep_learning/images/bird_0.jpg output:=/home/USR/catkin_ws/src/ros_deep_learning/test/output_0.jpg

End of the result:

[TRT]    imageNet -- loaded 1000 class info entries

[ERROR] [1640218246.217162196]: [setParam] Failed to contact master at [localhost:11311].  Retrying...

My system: Ubuntu 18.04, aarch64, ros melodic

echo $ROS_MASTER_URI 

http://localhost:11311

Any ideas of how to fix this? Any help is greatly appreciated!
