Which of cause presumes your filling_values is not something like 0 or [0]. Now it can be a code bug or just undocumented feature that filling_values can not a single zero. Thus something like these work: np.genfromtxt(StringIO(data), delimiter=",", names="a,b,c", filling_values=-90) np.genfromtxt(StringIO(data), delimiter=",", names="a,b,c", filling_values=[0,0]) np.genfromtxt(StringIO(data), delimiter=",", names="a,b,c", filling_values=[0,0,0]) Bruce _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
