How to get Python import working with dlib (using cmake and osx)

Question

Sorry if this is basic but I'm trying to install dlib to use with python as mentioned in (http://blog.dlib.net/2014/04/dlib-187-released-make-your-own-object.html) "Make your own object detector in Python!".

I downloaded the install files, unzipped, and used cmake as in the install instructions (http://dlib.net/compile.html)

cd examples
mkdir build
cd build
cmake ..
cmake --build . --config Release

which seemed to work fine

However typing "import dlib" in Python just gives ImportError: No module named dlib.

Any idea how I tell Python how to find / use the thing?

Answer 1

Just a note for reference that the easiest way to install is now to use:

sudo python setup.py install

Answer 2

Instead of manual file editing, you can pass -DPYTHON_LIBRARY:FILEPATH=/path/to/your/libpython2.7.dylib to cmake.

What ./compile_dlib_python_module.bat does is

mkdir build
cd build
cmake ../../tools/python

So, just run the commands by one by one and instead of

cmake ../../tools/python

run

cmake ../../tools/python -DPYTHON_LIBRARY:FILEPATH=/usr/local/Cellar/python/2.7.8/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib
