No module named 'pyopengv'

[angussmitchell]

Hi all, after installing successfully on Ubuntu18.04, I cannot run the test.py code in the python directory - I get the error
ModuleNotFoundError: No module named 'pyopengv'

To install I ran:

git clone https://github.com/laurentkneip/opengv --recurse-submodules
sudo apt-get install build-essential
sudo apt-get install cmake
sudo apt-get install cmake libeigen3-dev
cd opengv && mkdir build && cd build && cmake .. -DBUILD_PYTHON=ON -DEIGEN_INCLUDE_DIR:STRING="/home
/a/subterra/video-processing/eigen-3.3.7" && make

The build output is as follows:

You need to run sudo make install in the build folder after compilation.
