view window freezes after launching

[edanweis]

After launching, a window appears, and weights are correctly loaded, but then the window freezes with no error message. The window appears black

What could be wrong ?

You will have to remap the input for /camera/image_raw to your desired image topic.

@ayushgaud Sorry, I'm new to ROS. I am running usb_cam node and have changed the object_detect.launch to <remap from="usb_cam/image_raw" to="/camera/rgb/image_raw"/> But still getting a frozen window.

Fixed with <remap from="/camera/image_raw" to="/usb_cam/image_raw"/>
