But it came across many communication error Found 24 error(s).

ERROR Communication with [/camera/depth/metric] raised an error: ERROR Communication with [/camera/driver] raised an error: ERROR Communication with [/camera/register_depth_rgb] raised an error: ERROR Communication with [/camera_base_link] raised an error: ERROR Communication with [/camera/ir/rectify_ir] raised an error: ERROR Communication with [/camera/depth_registered/metric_rect] raised an error: ERROR Communication with [/camera/depth_registered/rectify_depth] raised an error: ERROR Communication with [/rosout] raised an error: ERROR Communication with [/camera/rgb/rectify_mono] raised an error: ERROR Communication with [/camera/depth/rectify_depth] raised an error: ERROR Communication with [/camera/depth/metric_rect] raised an error: ERROR Communication with [/camera_nodelet_manager] raised an error: ERROR Communication with [/rviz_1343258123122945215] raised an error: ERROR Communication with [/camera/rgb/rectify_color] raised an error: ERROR Communication with [/camera/depth_registered/metric] raised an error: ERROR Communication with [/camera_base_link1] raised an error: ERROR Communication with [/camera_base_link3] raised an error: ERROR Communication with [/camera_base_link2] raised an error: ERROR Communication with [/camera/points_xyzrgb_depth_rgb] raised an error: ERROR Communication with [/camera/depth/points] raised an error: ERROR Communication with [/camera/disparity_depth] raised an error: ERROR Communication with [/camera/rgb/debayer] raised an error: ERROR Communication with [/camera/disparity_depth_registered] raised an error: ERROR The following nodes should be connected but aren't:
