You're _still_ not passing into `load_from_yahoo` either `indexes` or 
`stocks` parameters, as I tried to point out by highlighting:

     assert indexes is not None or stocks is not None, """

Either `indexes` must have a value or stocks must.

Which is exactly what the error is telling you.

This isn't a dependency issue. You just need to read the documentation, 
work out what format it requires indexes or stocks to be specified in, 
and then pass them to `load_from_yahoo`. Calling it without _any_ 
arguments will give you the exception you're seeing.

Look at the file examples/dual_moving_average.py, it shows you exactly 
what you need:

     data = load_from_yahoo(stocks=['AAPL'], indexes={}, start=start,
                            end=end)
