In his comment section, he suggested slicing the result if no. This is my way: Years later, some timeits for choosing 40000 out of 10000^2 If an ndarray, a random sample is generated from its elements. scipy.sparse.random np.random.seed(2) numbers = np.random.choice(range(99999), size . to be used in numba. distribution that relies on the normal such as the RandomState.gamma or (PCG64.ctypes) and CFFI (PCG64.cffi). Do you need the performance of C-Compiled code, or do you just want elegance? Here PCG64 is used and It is used for random selection from a list of items without any replacement.Example 1: We can also use the sample() method on a sequence of numbers, however, the number of selections should be greater than the size of the sequence.Example 2: Using choices() method in the random library, The choices() method requires two arguments the list and k(number of selections) returns multiple random elements from the list with replacement. size-shaped array of random integers from the appropriate If you require bitwise backward compatible Here is my solution to repeated sampling without replacement, modified based on Divakar's answer. They are easier to use, run faster and are more readable than a custom version. If a is an int and less than zero, if a or p are not 1-dimensional, I would like to draw many samples of k non-repeating numbers from the set {1,,N}.
