Was macht numpy.random.seed(0)? tf.random.set_seed(89) As previously mentioned, all of this code needs to be at the start of your program. So, when you ran random.randint(25,50) second time, your seed was 42 and not 30. Here we will see how we can generate the same random number every time with the same seed value. 3 changed files. The seed value needed to generate a random number. random. Make sure you use np.empty(100000) to do this. 重复一次,seed函数是为了保证生成的数序列相同,而不是保证每次生成的值相同。, https://blog.csdn.net/linzch3/article/details/58220569. This thread is archived. How Seed Function Works ? >>> from numpy.random import MT19937 >>> from numpy.random import RandomState, … get_state Return a tuple representing the internal state of the generator. share. They are returned as a NumPy array. View clear_bin.py from COMPUTER S 4771 at Columbia University. These examples are extracted from open source projects. plain copy Showing. Can be any integer between 0 and 2**32 - 1 inclusive, an array (or other sequence) of such integers, or None (the default). Syntax : numpy.random.rand(d0, d1, ..., dn) Parameters : d0, d1, ..., dn : [int, optional]Dimension of the returned array we require, If no argument is given a single Python float is returned. The "seed" is used to initialize the internal pseudo-random number generator. The output of the code sometime depends on input. As Fishtoaster mentioned, the number 42 has gained pop-culture status via Douglas Adams's Hitchhiker's Guide to the Galaxy, but its true origins are from Lewis Carroll (from … 重复一次,seed函数是为了保证生成的数序列相同,而不是保证每次生成的值相同。, renzimingcc: generate link and share the link here. seed (42) X, y = make_classification (n_samples = 10, n_features = 4, n_classes = 2, n_clusters_per_class = 1) y_true = y. reshape (-1, 1) Note that we do not split the data into the training and test datasets, as our goal would be to construct the network. If it is an integer it is used directly, if not it has to be converted into an integer. Default value is None, and … 这个函数的使用方法,在这里已经有前辈讲解过了,只是自己在测试的时候有一些思考,所以便写了这篇博客。下面是前辈文章的原话:, seed( ) 用于指定随机数生成时所用算法开始的整数值,如果使用相同的seed( )值,则每次生成的随即数都相同,如果不设置这个值,则系统根据时间来自己选择这个值,此时每次生成的随机数因时间差异而不同。, 可以看到,和上一份代码的运行结果不同。这里每次的输出结果都是不一样的。这也就提醒了我们在以后编写代码的时候要明白一点:random.seed(something)只能是一次有效。其实仔细想想也很自然,如果不是一次有效,比如说是一直有效,那岂不是会影响到后续的代码中随机数的选取?, 这次测试的代码比较可以说是很简单的,但是却暴露了我的一个思维上的漏洞:在这次测试中我虽然明白了:, 这段话的意思,但是我却先入为主地认为第二份代码的结果应和第一份代码中的一致。而通过反面思考,假设这个函数使用一次后便是一直有效的,那么每次生成的随即数都会相同,但是这样岂不是会影响到后续的代码中随机数的选取?, 所以,以后学新的东西的时候,都要问自己傻问题,不断地去测试自己的想法以达到更深的理解。, seed( ) 用于指定随机数生成时所用算法开始的整数值。 1.如果使用相同的seed( )值,则每次生成的随即数都相同; 2.如果不设置这个值,则系统根据时间来自己选择这个值,此时每次生成的随机数因时间差异而不同。 3.设置的seed()值仅一次有效, Castroy7: np.random.RandomState(42) what is seed value and what is random state and why crag use this its confusing. You need to run random.seed(30) again to set the seed back to its previous value.
