Roslaunch Problem #2

Open yuguanfeng opened 3 years ago

yuguanfeng commented 3 years ago

I have finished all the compiling steps successfully, but failed in the running. When I run: roslaunch dvs_global_flow ijrr_translation.launch it gives the error: ERROR:cannot launch node of type [dvs_displayer/dvs_displayer]:dvs_displayer ROS path [0]=/opt/ros/kinetic/share/ros ROS path [1]=/home/yuguanfeng/catkin_opticalflow/src/catkin_simple ROS path [2]=/home/yuguanfeng/catkin_opticalflow/src/rpg_dvs_ros/dvs_msgs ROS path [3]=/home/yuguanfeng/catkin_opticalflow/src/rpg_dvs_ros/davis_ros_driver ROS path [4]=/home/yuguanfeng/catkin_opticalflow/src/gflags_catkin ROS path [5]=/home/yuguanfeng/catkin_opticalflow/src/glog_catkin ROS path [6]=/home/yuguanfeng/catkin_opticalflow/src/dvs_global_flow_skeleton ROS path [7]=/opt/ros/kinetic/share Also along with: PluginManager._load_plugin() could not load plugin "rqt_image_view/ImageView": plugin not available But rqt_image_view has been tested successfully, I don't understand why it shows "plugin not available". I have Ubuntu16.04+ROS kinetic installed and already changed the rosbag path in the launch file.

Encounter the same problem. Have you solved it?
