Webb我们假设我们有1000个训练序列和200个测试序列。我们还需要为每个序列生成一个可能的输出序列，作为我们的目标值。我们可以使用numpy.random.randint函数来生成一些随机的整数作为输出序列，每个输出序列也有三个特征，并且长度为10。 Webb13 feb. 2024 · Example 1: Create a 1-D array using randint () # create a 1-D array a = np.random.randint(low = 1, size = 5) # print the newly created array print(a) [0 0 0 0 0] when low = 1 then randint () takes integer as 0. The size = 5 which creates a 1-D array. Now a 1-D array is created with integer as 0.

The randint() methods take an optional parameter named size, which is used to specify the number of random numbers to be generated. The generated random number will be returned in the form of a NumPy array. The simple syntax of creating an array of random numbers in NumPy looks like this:
WebbThe choice () method takes an array as a parameter and randomly returns one of the values. Example Get your own Python Server.
