Hi,

The error indicates you need to install OpenCV for the calibrator.

For JetPack 4.5, the python 3.6 and C++ version is installed by default.
Could you validate it first?

Thanks.

Because I upgraded opencv myself, but I forgot the original version of OpenCV. I think it’s only possible to go back to the original version of OpenCV
