I am using the ZedBoard for development, and the image is PYNQ v2.4. During development, I encountered an issue where the Ubuntu version is too low, and the compiled libraries do not support OpenCV4. The version of the compiled library libc6 is also low.
Hi @lumihuang,
Welcome to the PYNQ community.
Unfortunately, unless you find a pre compiled version that is compatible, you will have to build it from source code.
