Can't launch demo

See original GitHub issue

When I try to launch the demo, even though the example dataset is in place cortex.load gives the following error:

ds = cortex.load("/home/.../Research/pycortex/S1_retinotopy.hdf")
Traceback (most recent call last):

Have you installed pycortex to the system, IE running python setup.py install? You can’t run pycortex from the source directory because there is a compiled module. If you really want to run from the source directory, you’ll need to run python setup.py build_ext --inplace first.

Yep. The problem was example dataset was within the pycortex source folder. Moved it elsewhere, and it works. Thanks a bunch!
