Applications of super-mathematics to non-super mathematics, How to delete all UUID from fstab but not the UUID of boot filesystem. of samples is small, because argsort can take a long time. The random module gives access to various useful functions and one of them being able to generate random numbers, which is randint () . Making statements based on opinion; back them up with references or personal experience. It accepts a bit generator instance as an argument. For instance: #This is equivalent to np.random.randint(0,5,3), #This is equivalent to np.random.permutation(np.arange(5))[:3], array(['pooh', 'pooh', 'pooh', 'Christopher', 'piglet'], # random, Mathematical functions with automatic domain. Return random integers from the discrete uniform distribution of If that's not an issue, a faster solution would be to generate a sample s = np.random.randint (len (X)**2, size=n) and use s // len (X) and s % len (X) to provide the indices (since these simple operations are much faster than running the Mersenne Twister for the additional rounds, the speed-up being roughly a doubling).
