I have installed a package and cannot get it to work. I know that one of the possible reasons of this problem is incorrect (or not existing) values of certain environment variables. In particular, I know that I need to set PYTHONPATH and PYTHON_LIBRARY_PATH. To set the correct values for these variables I need to know their meaning.
For example, after the installation of the package, I got a directory with a lot of *.dll files. Should I use the name of this directory as a value for one of the two above mentioned environment variables?
I also have another directory (C:\OpenCV2.2\Python2.7\Lib\site-packages) that contains just two files: cv.lib and cv.pyd. Should I use this directory as a value for one of the above mentioned environment variables (people recommend that but I do not understand why).
PYTHONPATHis documentedPYTHON_LIBRARY_PATHis something I never heard of. That variable is not set in my environment and is not mentioned in the entire documentation. I also searched the entire python source code and that string is also not mentioned there. Where did you see about this variable? Maybe it is some vendor-specific thing?
