Hi @RustSon what is the error generated when the ROS node crashes?

[Myzhar]

I could run the nodes correctly.

In one terminal (I'm using a ZED2i now): $ roslaunch zed_wrapper zed2i.launch

In a second terminal: $ roslaunch darknet_ros darknet_ros.launch image:=/zed2i/zed_node/rgb/image_rect_color

Result:

There are surely many parameters to tune (e.g. red and blue channels must be flipped), but it worked with no issues for long time.

Sorry! I found that there was a problem with the USB3.0 port of my computer, which led to this bug. Thank you again for your help!
