random.uniform(shape, lower_bound, upper_bound, seed=None, *, name=None)

Create a sample of uniformly distributed random numbers.

  • shape (tuple) – The shape of the sampled random numbers.

  • lower_bound (float) – The inclusive lower bound of the interval of the uniform distribution.

  • upper_bound (float) – The exclusive upper bound of the interval of the uniform distribution.

  • seed (int or None, optional) – A seed for the random number generator. Defaults to None, in which case a random value for the seed is used.

  • name (str or None, optional) – The name of the node.
