Hi, I was wondering why histogram2d and histogramdd raise a ValueError when fed with empty data of the correct dimensions. I came across this as a corner case when calling histogram2d from my own specialized histogram function.
In comparison, histogram does handle this case correctly when bins are specified explicitely (obviously automatic binning cannot work without data...) np.histogram([], bins=([0,1])) (array([0]), array([0, 1])) np.histogram2d([],[], bins=([0,1],[0,1])) ValueError: zero-size array to ufunc.reduce without identity np.histogramdd([[],[]], bins=([0,1],[0,1])) ValueError: zero-size array to ufunc.reduce without identity cheers, nils _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
