title: Import Error Openpose in Python project with Mac OS
body: <p>I have installed OpenPose in MacOSX, and I can execute the examples like this:</p>
  
  <pre><code>'./build/examples/openpose/openpose.bin --video examples/media/video.avi'
  </code></pre>
  
  <p>But <strong>I cannot import/use the Openpose library in Python projects.</strong></p>
  
  <p>In Openpose folder I've done: </p>
  
  <pre><code>cd build/python
  sudo make install
  </code></pre>
  
  <p>And export variable:
  vim ~/.bashrc</p>
  
  <pre><code>#(Add this line to the end of the file)
  export PYTHONPATH=/path/to/openpose/build/python:
  </code></pre>
  
  <p>But when I try to import from Python console:</p>
  
  <pre><code>➜ python
  Python 2.7.10 (default, Oct  6 2017, 22:29:07)
  [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin

  &gt;&gt;&gt; import openpose
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named openpose
  </code></pre>
  
  <p>Any ideas on how to solve this to be able to use Openpose from a Python project?</p>
  
  <p>Thanks</p>
