## Bucketize <a name="Bucketize"></a> {#openvino_docs_ops_condition_Bucketize_3}

**Versioned name**: *Bucketize-3*

**Category**: Condition operation

**Short description**: *Bucketize* bucketizes the input based on boundaries. This is similar to [Reference](https://www.tensorflow.org/api_docs/cc/class/tensorflow/ops/bucketize).

**Detailed description**: *Bucketize* computes a bucket index for each element from the first input and outputs a tensor of the first input shape. Buckets are defined with boundaries from the second input.

For example, if the first input tensor is `[[3, 50], [10, -1]]` and the second input is `[0, 5, 10]` with included right bound, the output will be `[[1, 3], [2, 0]]`.

**Attributes**

* *output_type*

  * **Description**: the output tensor type
  * **Range of values**: "i64" or "i32"
  * **Type**: string
  * **Default value**: "i64"
  * **Required**: *no*

* *with_right_bound*

  * **Description**: indicates whether bucket includes the right or the left edge of interval.
  * **Range of values**:
    * true - bucket includes the right interval edge
    * false - bucket includes the left interval edge
  * **Type**: `boolean`
  * **Default value**: true
  * **Required**: *no*

**Inputs**:

*   **1**: N-D tensor of *T* type with elements for the bucketization. **Required.**
*   **2**: 1-D tensor of *T_BOUNDARIES* type with sorted unique boundaries for buckets. **Required.**

**Outputs**:

*   **1**: Output tensor with bucket indices of *T_IND* type. If the second input is empty, the bucket index for all elements is equal to 0. The output tensor shape is the same as the first input tensor shape.

**Types**

* *T*: any numeric type.

* *T_BOUNDARIES*: any numeric type.

* *T_IND*: `int32` or `int64`.
