Numpys random number routines produce pseudo random numbers using np.random.seed(1) gives unique set and so does np.random.seed(2). Rather, it is pseudorandom: generated with a pseudorandom number generator (PRNG), which is essentially any algorithm for generating seemingly random but still reproducible data. bit generator-provided stream and transforms them into more useful used which is suitable for high memory constraint or when Example-2: Use random.randint() to generate random array. Generates a random sample from a given 1-D array. Instead we can use pseudorandomness. single value is returned. routines. 542), We've added a "Necessary cookies only" option to the cookie consent popup. If not given, the sample assumes a uniform distribution over all randn methods are only available through the legacy RandomState. 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). Setting user-specified probabilities through p uses a more general but less Making statements based on opinion; back them up with references or personal experience.
