Outputs random values from a truncated normal distribution.

Used in the notebooks

Used in the guide

The generated values follow a normal distribution with specified mean and standard deviation, except that values whose magnitude is more than 2 standard deviations from the mean are dropped and re-picked.


  • shape: A 1-D integer Tensor or Python array. The shape of the output tensor.
  • mean: A 0-D Tensor or Python value of type dtype. The mean of the truncated normal distribution.
  • stddev: A 0-D Tensor or Python value of type dtype. The standard deviation of the normal distribution, before truncation.
  • dtype: The type of the output.
  • seed: A Python integer. Used to create a random seed for the distribution. See tf.compat.v1.set_random_seed for behavior.
  • name: A name for the operation (optional).


A tensor of the specified shape filled with random truncated normal values.
