I have seen this error in the past, I don't recall the exact conditions, but I think it means something is missing. The missing piece belongs to the libonvif python module, and may be the libxml2-dev installation. You could try the installation from source in verbose mode and see if you get a more descriptive error message.

sudo apt install git cmake g++ python3-pip libxml2-dev libavdevice-dev libsdl2-dev '^libxcb.*-dev' libxkbcommon-x11-dev

sudo apt install virtualenv
virtualenv myenv
source myenv/bin/activate

git clone --recursive https://github.com/sr99622/libonvif

cd libonvif/libonvif
pip install -v .
cd ../libavio
pip install  -v .
cd ../onvif-gui
pip install  -v .

@sr99622 Thank you for your reply this is what I got!

But I checked on several cases regarding of the import of cmake (install via pip) on internet but no found solution. Do you have any recommendation? I did try re-install things multiple times. and the import of cmake is ok if I do it separately

Oh I found it. Turns out I need to set correct PATH to /usr/bin/cmake instead of the cmake installed from pip.
