When I used "rosrun lidar_camera_calibration calibrate_camera_lidar.py --calibrate", the results were:

Press [ENTER] to pause and pick points [INFO] [1573844994.016894]: Current PID: [17218] [INFO] [1573844994.017239]: Projection mode: False [INFO] [1573844994.017417]: CameraInfo topic: /sensors/camera/camera_info [INFO] [1573844994.017584]: Image topic: /sensors/camera/image_color [INFO] [1573844994.017745]: PointCloud2 topic: /sensors/velodyne_points [INFO] [1573844994.017903]: Output topic: None

But it had no response and GUI when I press [ENTER].

Could someone help me with it ?
