*@brief Bucketize each feature based on bucket boundaries.

*@par Inputs:
*The input float_values can be 1-D tensor, bucket_boundaries can be 1-D. Inputs include: \n
* @li float_values: List of Rank 1 Tensor each containing float values for a single feature. \n
* @li bucket_boundaries:List of Rank 1 Tensors each containing the bucket boundaries for a single. \n

*@par Attributes:
*@li num_features:number of features \n

*@par Outputs:
*@li y:List of Rank 1 Tensors each containing the bucketized values for a single feature. \n

*@attention Constraints: \n
*-The implementation for BoostedTreesBucketize on Ascend uses AI CPU, with bad performance. \n

*@par Quantization supported or not
*Not supported
*@par Quantized inference supported or not
