# tensorflow::ops::DenseBincount Class Reference

DenseBincount

`
#include <math_ops.h>
`


Counts the number of occurrences of each value in an integer array.

## Summary


Outputs a vector with length
`
size
`
and the same dtype as
`
weights
`
. If
`
weights
`
are empty, then index
`
i
`
stores the number of times the value
`
i
`
is counted in
`
arr
`
. If
`
weights
`
are non-empty, then index
`
i
`
stores the sum of the value in
`
weights
`
at each index where the corresponding value in
`
arr
`
is
`
i
`
.


Values in
`
arr
`
outside of the range \[0, size) are ignored.


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- input: 1D or 2D int `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` .
- size: non-negative int scalar `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` .
- weights: is an int32, int64, float32, or float64 `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` with the same shape as `
  arr
  ` , or a length-0 `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` , in which case it acts as all weights equal to 1.

<br />


Optional attributes (see
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/struct/tensorflow/ops/dense-bincount/attrs#structtensorflow_1_1ops_1_1_dense_bincount_1_1_attrs
`
):

- binary_output: bool; Whether the kernel should count the appearance or number of occurrences.

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : 1D `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` with length equal to `
  size
  ` or 2D `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor
  ` with \[batch_size, `
  size
  ` \]. The counts or summed weights for each value in the range \[0, size).
