[docs]def seed(seed_state): """Seeds the random number generators in MXNet. This affects the behavior of modules in MXNet that uses random number generators, like the dropout operator and `NDArray`'s random sampling operators. Parameters ---------- seed_state : int The random number seed to set to all devices. Notes ----- Random number generators in MXNet are device specific. Therefore, random numbers generated from two devices can be different even if they are seeded using the same seed. Example ------- >>> print(mx.nd.random.normal(shape=(2,2)).asnumpy()) [[ 1.36481571 -0.62203991] [-1.4962182 -0.08511394]] >>> print(mx.nd.random.normal(shape=(2,2)).asnumpy()) [[ 1.09544981 -0.20014545] [-0.20808885 0.2527658 ]] >>> >>> mx.random.seed(128) >>> print(mx.nd.random.normal(shape=(2,2)).asnumpy()) [[ 0.47400656 -0.75213492] [ 0.20251541 0.95352972]] >>> mx.random.seed(128) >>> print(mx.nd.random.normal(shape=(2,2)).asnumpy()) [[ 0.47400656 -0.75213492] [ 0.20251541 0.95352972]] """ if not isinstance(seed_state, int): raise ValueError('sd must be int') seed_state = ctypes.c_int(int(seed_state)) check_call(_LIB.MXRandomSeed(seed_state))
