Hi,
I run stereo_image_proc  by

                 <node ns="stereo" pkg="stereo_image_proc" type="stereo_image_proc" respawn="false" name="stereo_image_proc" args="_approximate_sync:=True">
                   <!--remap from="stereo_image_proc/parameter_descriptions" to="parameter_descriptions" />
                   <remap from="stereo_image_proc/parameter_updates" to="parameter_updates" /-->
                 </node>


It crashes and returns the below message when I attempt to view the images by stereo_view

process[stereo/stereo_image_proc-1]: started with pid [6045]
