My environment: Jetpack4.3 in Jetbot0.4.0 ROS2 Eloquent is installed through Debian package, so install folder is /opt/ros/eloquent. ros2_trt_pose is installed ~/ros2_ws/src/ros2_trt_pose Camera: CSI 

jetbot@jetson-4-3:~$ ls /dev/video*
/dev/video0

Before run ros2_trt_pose

source /opt/ros/eloquent/local_setup.bash
source ~/ros2_ws/src/ros2_trt_pose/install/local_setup.sh

"image_tools cam2image" doesn't show any error message. jetbot@jetson-4-3:~$ ros2 run image_tools cam2image [INFO] [cam2image]: Publishing image #1 [INFO] [cam2image]: Publishing image #2 [INFO] [cam2image]: Publishing image #3 [INFO] [cam2image]: Publishing image #4 [INFO] [cam2image]: Publishing image #5 [INFO] [cam2image]: Publishing image #6 [INFO] [cam2image]: Publishing image #7 [INFO] [cam2image]: Publishing image #8 [INFO] [cam2image]: Publishing image #9 [INFO] [cam2image]: Publishing image #10 [INFO] [cam2image]: Publishing image #11 [INFO] [cam2image]: Publishing image #12 :

Though I got below error.

[pose-estimation-1] Matplotlib created a temporary config/cache directory at /tmp/matplotlib-0pj0a0do because the default path (/home/jetbot/.cache/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.
[pose-estimation-1] Matplotlib is building the font cache; this may take a moment.
[ERROR] [cam2image-2]: process has died [pid 4004, exit code -6, cmd '/opt/ros/eloquent/lib/image_tools/cam2image --ros-args -r __node:=cam'].

Any suggestion to solve this problem?

Thanks!

Can you check if cam2image is publishing any image by using ros2 run image_tools cam2image?
