在 Python 中运行 numpy.random.randint() 后冻结输出

Question

I've used numpy.random.randint(lower limit, upper limit, size) to make a 2D array with random numbers within the given range. Now I want to freeze this randomly generated array for the follow up steps. So that the numbers don't change every time I run the entire script. Is there a way to do this?

Thanks.

Answer 1

Set a seed so that the random numbers generated are same every time you run it.

numpy.random.seed(0)

Answer 2

By seeding random by hand you can get the same random number whenever you call it. You can seed the random() function using seed() function. The input is the seed and the same seed input will result the same output.

from numpy import random

random.seed(1)
first = random.randint(10)

random.seed(1)
second = random.randint(10)

In this code both first and second will be same.
