I know that to seed the randomness of numpy.random, and be able to reproduce it, I should us: importnumpyasnp np.random.seed(1234) but what doesnp.random.RandomState()do? python numpy random Share Copy link Improve this question

方法二是整数数组索引,将需要索引的三个位置上的数的一维索引值,用中括号+逗号的方式选出,再将二维索引值写出)。 2. 布尔索引 通过布尔运算(如:比较运算符)来获取符合指定条件的元素的数组。 例1: x=np.array([[0,1,2],[3,4,5],[6,7,8],[9,10,11]]) ...
