No such file or directory: '/home/xxx/.ros/xarm_vision/color_recognition.yaml'

When I run the color block recognition demo under xarm_vision/camera_demo, I keep getting the error: read parameters from yaml failed, [Errno 2] No such file or directory: '/home/xxx/.ros/xarm_vision/color_recognition.yaml', how to solve this? I don't see anything in the code that can generate a yaml file
