gen_calibration.py: unable to read 32db.xml
3D lidar : HDL-64E S3 , ubuntu 14.04 indigo
when I operate the lidar HDL-64E S3 as the tutorial "http://wiki.ros.org/velodyne/Tutorials/Getting%20Started%20with%20the%20HDL-32E" and run command "rosrun velodyne_pointcloud gen_calibration.py 32db.xml" , will appear as the following: converting "32db.xml" to "32db.yaml" gen_calibration.py: unable to read 32db.xml
why ? I have checked that there is 32db.xml in the package.
someone can help me?
thanks!!
