Sorry for all.
It works when I re-downloaded ZED SDK for JEtPack 5.1.1 and installed all the options with ‘Y’
(when I had installed before, I denied some options because I don’t need AI recognition)
And I recommend that try to launch python file before installing ZED Python API.
But I’m still wondering that the ZED SDK for JetPack 5.1.1 is the latest one and updating the Jetpack version
