[IPython-user] Easy way to get the equivalent of python -W all in ipython ?

[David Cournapeau]

Hi,

    Debugging some numerical code which underflow, I would like to see 
any warning related to underflow, even if it appears several times from 
the same location. In python, I can do python -W all for this.
    What should I do in ipython for the same effect ?

    thank you
