使用 random.seed：

 placeholderCopynp.random.seed(0)
np.random.rand(5)
# Out: array([ 0.5488135 ,  0.71518937,  0.60276338,  0.54488318,  0.4236548 ])

通過建立隨機數生成器物件：

 placeholderCopyprng = np.random.RandomState(0)
prng.rand(5)
# Out: array([ 0.5488135 ,  0.71518937,  0.60276338,  0.54488318,  0.4236548 ])
