title: Installation of COCOAPI for python 3.5.2
body: <p>I've heard that there's python version incompatibility issues with the original COCOAPI and that it doesn't work with python 3? And so I'm using this version: 
  <a href="https://github.com/philferriere/cocoapi" rel="nofollow noreferrer">https://github.com/philferriere/cocoapi</a></p>
  
  <p>But I'm facing similar issues as when I was using the original COCOAPI.</p>
  
  <p>after running: pip install git+<a href="https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI" rel="nofollow noreferrer">https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI</a>,
  I managed to get: Successfully built pycocotools</p>
  
  <p>When I tried to make under the PythonAPI folder:
  .../cocoapi-master/PythonAPI$ make</p>
  
  <p>It returned without any errors:
  python setup.py build_ext --inplace
  running build_ext
  rm -rf build</p>
  
  <p>However, when I tried running: .../cocoapi-master/PythonAPI$ python Makefile
  I keep getting this error:
  File "Makefile", line 1
  all:
  ^
  SyntaxError: invalid syntax</p>
  
  <p>When I tried running: .../cocoapi-master/PythonAPI/demos$ python pycocoDemo.ipynb
  I get this error:
  Traceback (most recent call last):
  File "pycocoDemo.ipynb", line 7, in 
  "collapsed": true
  NameError: name 'true' is not defined</p>
  
  <p>Prior to this, I've tried running and installing the original cocoapi (<a href="https://github.com/cocodataset/cocoapi/tree/master/PythonAPI" rel="nofollow noreferrer">https://github.com/cocodataset/cocoapi/tree/master/PythonAPI</a>) but it gave similar errors. I searched around and tried installing extra packages, upgrading pip version, etc, but none of it is working...Would someone please advise me? Your help would be greatly appreciated!!!</p>
  
  <p>Python version: 3.5.2,
  Pip version: 18.0,
  Cython version: 0.28.5,
  pycocotools-2.0,
  numpy.version.version: '1.14.2'</p>
