Import Error : C Extension while generating windows executable of a Python script using PyInstaller

Question

Import error: C extension: NO MODULE NAMED TIMEDELTAS NOT BUILT. If you want to import PANDAS from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.

I tried following things up to now but couldn't resolve this :

• pip install --upgrade pip

• pip install --upgrade pandas

• uninstalled the existing version of pandas and installed again.

• pip install Cython

Please look at the SCREENSHOT ATTACHED ABOVE SHOWS VERSION of PANDAS, NUMPY, PYTZ, SIX installed on my system.

NOTE : I'm using Python 2.7

Any help on this will be appreciated. Thanks.
