[Bug] Unable to build opencv container with the default opencv tag 4.8.1

[hrishi121]

Hello,

I have been trying to build the NanoLLM container for following system config:

Jetson Orin NX
-- L4T_VERSION=36.3.0
-- JETPACK_VERSION=6.0
-- CUDA_VERSION=12.4
-- PYTHON_VERSION=3.10
-- LSB_RELEASE=22.04 (jammy)

One of the dependencies for the NanoLLM container is the opencv container. When building the opencv container, I noticed that install.sh would fail and it would proceed to build the opencv-python repo using the build.sh script. However, compiling opencv-python from scratch with the build.sh would keep failing as well (Unfortunately, I forgot to capture the build errors)

I commented out the following lines in build.sh, and was able to build the opencv container

#git checkout --recurse-submodules ${OPENCV_VERSION}
#cat modules/core/include/opencv2/core/version.hpp

#cd ../opencv_contrib
#git checkout --recurse-submodules ${OPENCV_VERSION}

#cd ../opencv_extra
#git checkout --recurse-submodules ${OPENCV_VERSION}

Commenting out these lines disables the build from using the 4.8.1 submodules for opencv, opencv_contrib, opencv_extras and rather use the new default 4.10.0 submodules in the 4.x branch

I am not totally sure why the build was failing earlier, but my guesses are:

• Incompatibility of CUDA 12.4 with the 4.8.1 submodules
• [OR] Incompatibility of the latest opencv-python branch 4.x with 4.8.1 submodules

Just wanted to give a heads-up to anyone who is building any container that has the opencv as a dependency and using CUDA 12.4

@dusty-nv Is there a specific reason for using 4.8.1 as the default opencv version in config.py ? Do you think it would be a good idea to update it to 4.10.0 ?

FYI I'm using opencv 4.10 with cuda 12.6 cudnn last version without problems
