rosrun jsk_perception image_publisher.py does not work (?)

[k-okada]

I followed instruction and start

rosrun jsk_perception image_publisher.py _file_name:=$(rospack find jsk_perception)/sample/object_detection_example_1.jpg

and try to visualize the image by

 rosrun image_view image_view image:=/image_publisher/output
[ERROR] [1634453747.476164744]: Skipped loading plugin with error: XML Document '/opt/ros/noetic/share/prosilica_camera/plugins/nodelet_plugins.xml' has no Root Element. This likely means the XML is malformed or missing..
[ INFO] [1634453747.480691611]: Initializing nodelet with 12 worker threads.
[ INFO] [1634453747.555356635]: Using transport "compressed"

but it does not work. Using image_publisher works.

rosrun image_publisher image_publisher $(rospack find jsk_perception)/sample/object_detection_example_1.jpg __name:=image_publisher ~image_raw:=~output

This because I ran

rosrun image_view image_view image:=/edgetpu_object_detector/output/image _image_transport:=compressed

and it update /image_view/image_transport as follows

$ rosparam get /image_view/image_transport
compressed

but image_publishser.py does not support compressed format, to reset transport hint. Ran

rosrun image_view image_view  image:=/image_publisher/output　_image_transport:=raw

Or wait for jsk-ros-pkg/jsk_recognition#2637
