I enter the ‘sudo apt-get install libopencv4tegra libopencv4tegra-dev’,error is:

Hi Jiao2304,
Jetpack3.1 would help install all the dependencies. Why do you want to install o4v by using apt-get?
yes,if I use the Jetpack for tx2,the opencv can installde successfully,but I use the apt-get ,there is some errors.
and I have solved it ,after ‘apt-get update’,I use ‘sudo apt-add-repository universe’,It is ok.

The official “L4T-R28.1 Release Notes” actually says OpenCV4Tegra is deprecated…
https://developer.nvidia.com/embedded/dlc/l4t-release-notes-28-1
2.4 OpenCV4Tegra Deprecated
OpenCV4Tegra Version 2.4.13 is provided as deprecated in Release 28.1. OpenCV4Tegra provides CPU and GPU enabled acceleration for OpenCV Version 2.4.13. These improvements have been integrated into the OpenCV project in version 3.2. Users of OpenCV must upgrade to OpenCV Version 3.2 and obtain support from the OpenCV community.
ok,thank you for you reply.
