Outstanding! Worked the first time. Thanks

Which version of Ubuntu have you used for installing it? I am installing it on Ubuntu 16.04.7 on a VirtualBox (Win 10), but get errors.

Thanks. It worked on python 2.7.12. (which is my default one). How to make it work on python 3.5?

Hello, I also want to make it work on Python 3.5/3.5+ -- any luck getting it worked on Python 3.5+?

Everything goes fine until I run the following command.

"sudo apt-get -qq install libopencv-dev build-essential checkinstall
cmake pkg-config yasm libjpeg-dev libjasper-dev libavcodec-dev
libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev
libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev
python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev
libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev
libvorbis-dev libxvidcore-dev x264 v4l-utils"

When I run the above command, it gives me the following error:

"E: Package 'libxine-dev' has no installation candidate"

I have python 3.8.9 installed on Ubuntu 16.04.7
