Could not get sonar data.

Hello, I connected M750d sonar to my computer, and I also run the roslaunch sonar_oculus sonar_oculus.launch, but I can not get image in rqt.

hello, I finally connected the sonar successfully. I uninstalled the opencv-python and used the 4.1.1 opencv in Jetpack 4.6.1, then the driver worked. But I also found new issue, there were two lines on the sonar photo, and I checked my M750D and M1200D sonar, both of them were OK, have you met similar issue before?
