Unable to start after installation

[ishwarvh]

Installation was successful, however when I try to run the application, I get the following error message:

$ python app.py
Traceback (most recent call last):
  File "app.py", line 1, in <module>
    from PyQt5 import QtCore, QtGui, QtWidgets
ImportError: dlopen(/Applications/anaconda/lib/python3.5/site-packages/PyQt5/QtCore.abi3.so, 2): Symbol not found: __os_activity_create
  Referenced from: /Applications/anaconda/lib/python3.5/site-packages/PyQt5/Qt/lib/QtCore.framework/Versions/5/QtCore (which was built for Mac OS X 10.13)
  Expected in: /usr/lib/libSystem.B.dylib
 in /Applications/anaconda/lib/python3.5/site-packages/PyQt5/Qt/lib/QtCore.framework/Versions/5/QtCore

Triple checked PyQt5 installation. All the requirements in the requirements.txt have been satisfied.
I am running it on OSX El Capitan 10.11.6

Any suggestions on how to resolve this?

Thanks
