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

tf.raw_ops.Bincount( arr, size, weights, name=None )

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 | |
---|---|

`arr` | A `Tensor` of type `int32` . int32 `Tensor` . |

`size` | A `Tensor` of type `int32` . non-negative int32 scalar `Tensor` . |

`weights` | A `Tensor` . Must be one of the following types: `int32` , `int64` , `float32` , `float64` . is an int32, int64, float32, or float64 `Tensor` with the same shape as `arr` , or a length-0 `Tensor` , in which case it acts as all weights equal to 1. |

`name` | A name for the operation (optional). |

Returns | |
---|---|

A `Tensor` . Has the same type as `weights` . |
