tf.random.get_global_generator() ### Used in the notebooks | Used in the guide | |---| | - [Random number generation](https://www.tensorflow.org/guide/random_numbers) | This function will create the global generator the first time it is called, and the generator will be placed at the default device at that time, so one needs to be careful when this function is first called. Using a generator placed on a less-ideal device will incur performance regression.
