It did at some point (and I relied on the exception to catch bugs, since I'm still using mainly numpy 1.5) >>> f1 = [[15.207, 15.266, 15.181, 15.189, 15.215, 15.198], [-45, -57, -62, >>> -70, -72, -73.5, -77]] >>> np.array(f1) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: setting an array element with a sequence. >>> np.__version__ '1.5.1' now we get object arrays (in scipy.stats, and I didn't know what to do with them) I don't remember any discussion on this.
