Problem installing libopencv in 4t-pytorch:r34.1.1-pth1.12-py3

[jnaranjo]

Hi everybody I am trying to install libopencv in nvcr.io/nvidia/l4t-pytorch:r34.1.1-pth1.12-py3
However, I get the following output:

dpkg: error processing archive /tmp/apt-dpkg-install-KGW73W/105-libopencv_4.5.4-8-g3e4c170df4_arm64.deb (--unpack):

Any ideas in how to solve this issue?
Thanks in advance!

Hi,

It looks like there are already some OpenCV files exist.

Could you share which command you execute?
Have you installed it with sudo?

Thanks.

I run a Dockerfile

FROM 4t-pytorch:r34.1.1-pth1.12-py3
RUN apt-get install libopencv

It seems this NVIDIA Docker image has already installed some opencv packages that are in conflict when installing libopencv

Hi @jnaranjo, yes that container already has OpenCV 4.5 installed that was built with support for CUDA enabled.
If you don’t want that, you can try running this in your Dockerfile instead:

RUN apt-get purge -y '*opencv*' && apt-get install -y libopencv

Okey! Thank you so much for the quick reply!
