The SVN version of np.genfromtxt will let you know where some rows are  
longer than others. You can decide what to do from then (ignore the  
corresponding rows or modify your file).
The .fromfile approach is a solution if you don't really care about  
getting a 2D array (or structured 1D array with different fields for  
ints and floats on a same row), as a previous poster illustrated.
