Hello,

According to https://ngc.nvidia.com/catalog/containers/nvidia:l4t-ml OpenCV version in l4t-ml:r32.5.0-py3 shoud be 4.4.1 while it seems to be 4.1.1 (same as L4T 32.5 base system)

takeshiba@jetsonnano2g:~$ docker run -it --rm --runtime nvidia --network host nvcr.io/nvidia/l4t-ml:r32.5.0-py3
allow 10 sec for JupyterLab to start @ http://localhost:8888 (password nvidia)
JupterLab logging location:  /var/log/jupyter.log  (inside the container)
root@jetsonnano2g:/# python3
Python 3.6.9 (default, Oct  8 2020, 12:12:24) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.1.1'

Is this a typo in https://ngc.nvidia.com/catalog/containers/nvidia:l4t-ml or am I missing something?

Thanks.

BTW: 4.4.1 Would make me happy

Hi @bin_nvidia, sorry it is a typo, the version in the container is the same as on the host (OpenCV 4.1.1). It is the same package from the host that is installed into the container.

If you want to change it, you can create your own container using l4t-ml as a base and re-builds OpenCV, or you can edit the l4t-ml Dockerfile and rebuild l4t-ml here: GitHub - dusty-nv/jetson-containers: Machine Learning Containers for NVIDIA Jetson and JetPack-L4T
