I always get the following error if I want to install OpenVino ROS2 on Ubuntu 18.04 via environment_setup.sh:
gpg: can't open '/home/.../code/open_model_zoo/demos/build/C8B3A55A6F3EFCDE' : No such file or directory
An if I start: ros2 launch dynamic_vino_sample pipeline_people.launch.py
I will get the following error:
Package 'dynamic_vino_sample' not found: "package 'dynamic_vino_sample' not found, searching: ['/opt/ros/dashing']"
I suggest you to ask the question in ROS2 github https://github.com/intel/ros2_openvino_toolkit and you might get the better answer. Since here the questions are targeting on standard OpenVINO.
