# tf.random.stateless_parameterized_truncated_normal

Outputs random values from a truncated normal distribution.

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.

#### Examples:

Sample from a Truncated normal, with deferring shape parameters that broadcast.

````means = 0.`
`stddevs = tf.math.exp(tf.random.uniform(shape=[2, 3]))`
`minvals = [-1., -2., -1000.]`
`maxvals = [[10000.], [1.]]`
`y = tf.random.stateless_parameterized_truncated_normal(`
`  shape=[10, 2, 3], seed=[7, 17],`
`  means=means, stddevs=stddevs, minvals=minvals, maxvals=maxvals)`
`y.shape`
`TensorShape([10, 2, 3])`
```

`shape` A 1-D integer `Tensor` or Python array. The shape of the output tensor.
`seed` A shape [2] Tensor, the seed to the random number generator. Must have dtype `int32` or `int64`. (When using XLA, only `int32` is allowed.)
`means` A `Tensor` or Python value of type `dtype`. The mean of the truncated normal distribution. This must broadcast with `stddevs`, `minvals` and `maxvals`, and the broadcasted shape must be dominated by `shape`.
`stddevs` A `Tensor` or Python value of type `dtype`. The standard deviation of the truncated normal distribution. This must broadcast with `means`, `minvals` and `maxvals`, and the broadcasted shape must be dominated by `shape`.
`minvals` A `Tensor` or Python value of type `dtype`. The minimum value of the truncated normal distribution. This must broadcast with `means`, `stddevs` and `maxvals`, and the broadcasted shape must be dominated by `shape`.
`maxvals` A `Tensor` or Python value of type `dtype`. The maximum value of the truncated normal distribution. This must broadcast with `means`, `stddevs` and `minvals`, and the broadcasted shape must be dominated by `shape`.
`name` A name for the operation (optional).

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