RandomGamma

`
#include <random_ops.h>
`


Outputs random values from the Gamma distribution(s) described by alpha.

## Summary


This op uses the algorithm by Marsaglia et al. to acquire samples via transformation-rejection from pairs of uniform and normal random variables. See
<http://dl.acm.org/citation.cfm?id=358414>


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- shape: 1-D integer tensor. Shape of independent samples to draw from each distribution described by the shape parameters given in alpha.
- alpha: A tensor in which each scalar is a "shape" parameter describing the associated gamma distribution.

<br />


Optional attributes (see
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/struct/tensorflow/ops/random-gamma/attrs#structtensorflow_1_1ops_1_1_random_gamma_1_1_attrs
`
):

- seed: If either `
  seed
  ` or `
  seed2
  ` are set to be non-zero, the random number generator is seeded by the given seed. Otherwise, it is seeded by a random seed.
- seed2: A second seed to avoid seed collision.

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : A tensor with shape `
  shape + shape(alpha)
  ` . Each slice `
  [:, ..., :, i0, i1, ...iN]
  ` contains the samples drawn for `
  alpha[i0, i1, ...iN]
  ` . The dtype of the output matches the dtype of alpha.
