python numpy random

np.random.rand(d0,d1,...,dn)#Create an array of the given shape and populate it#with random samples from a uniform distribution over# [0, 1).np.random.rand(3,2)#输出array([[ 0.14022471,  0.96360618],  #random       [ 0.37601032,  0.25528411],  #random       [ 0.49313049,  0.94909878]]) #random
