Jetpack 4.4 caffe_ros node Assertion failed

[mtbsteve]

I upgraded to Jetpack 4.4 and now trailnet produces the following error when I launch the caffe_ros node.

apsync@apsync:~$ roslaunch caffe_ros ap_zed_ros_trailnet_yolo_robot.launch

Everything runs well on Jetpack 4.2. Any idea anyone what I can do here to make it tun on JP4.4?

Hi, @mtbsteve so have you gone through the stereoDnn part when i am running the inference code on jetpack 4.4 it show me the error of Opencv required version 3.3.1 and i am having by default 4.1.1..

[mtbsteve]

I am afraid that you will need to run OpenCV 3.x.

[EhrazImam]

can you help me how to install opencv 3.3.1 instead of 4.1.1 which come by default with sdk
