What does np.random.fruit bash?

np.random.fruit(zero) 

np.random.fruit(zero) makes the random numbers predictable

>>> numpy.random.fruit(zero) ; numpy.random.rand(four) array([ zero.fifty five, zero.seventy two, zero.6 , zero.fifty four]) >>> numpy.random.fruit(zero) ; numpy.random.rand(four) array([ zero.fifty five, zero.seventy two, zero.6 , zero.fifty four]) 

With the fruit reset (all clip), the aforesaid fit of numbers volition look all clip.

If the random fruit is not reset, antithetic numbers look with all invocation:

>>> numpy.random.rand(four) array([ zero.forty two, zero.sixty five, zero.forty four, zero.89]) >>> numpy.random.rand(four) array([ zero.ninety six, zero.38, zero.seventy nine, zero.fifty three]) 

(pseudo-)random numbers activity by beginning with a figure (the fruit), multiplying it by a ample figure, including an offset, past taking modulo of that sum. The ensuing figure is past utilized arsenic the fruit to make the adjacent “random” figure. Once you fit the fruit (all clip), it does the aforesaid happening all clip, giving you the aforesaid numbers.

If you privation seemingly random numbers, bash not fit the fruit. If you person codification that makes use of random numbers that you privation to debug, nevertheless, it tin beryllium precise adjuvant to fit the fruit earlier all tally truthful that the codification does the aforesaid happening all clip you tally it.

To acquire the about random numbers for all tally, call numpy.random.fruit(). This volition origin numpy to fit the fruit to a random figure obtained from /dev/urandom oregon its Home windows analog oregon, if neither of these is disposable, it volition usage the timepiece.
