As long as the "publish_detections" parameter is set to true (which it is by default), the bounding boxes and masks will be published on the topic "/yolact_ros/detections". If you want to check whether this is working, you can use rostopic tools, e.g. "rostopic echo /yolact_ros/detections". To use them in another ROS node, you can subscribe to the topic (Python Tutorial / C++ Tutorial).

As mentioned in my previous reply, you have to subscribe to /yolact_ros/detections. If you renamed the node, the namespace changes. Do you get output for rostopic echo /yolact_ros/detections? If not, try rostopic list to check which topics are available.
