Is np.random.randint(2, size=N) the fastest way to do this? Thanks! DG ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

Sebastian, I apologize, that did work. I forgot to autoreload. Can you explain why the original code did work at the debug prompt? -Dave On Sun, Sep 22, 2013 at 10:45 AM, David Reed wrote: > Thanks Sebastian, but still have same error. Also doesn't explain why it > works when I run the same

Thanks Sebastian, but still have same error. Also doesn't explain why it works when I run the same code at the debug prompt. Scratching my head on this one. Dave On Sun, Sep 22, 2013 at 10:42 AM, Sebastian Berg wrote: > On Sun, 2013-09-22 at 10:21 -0400, David Reed wrote: > > Hi, > > > > > >

Hi, I am getting a strange error when finding the minimum of a matrix. The weird thing is I get this while running within iPython shell, and if I do %debug and go to the line where this fails and run the command `a = np.min(D, axis=0)`, I get no error. Here is the trace: draw_lines/main.pyc in
