BatchToSpaceND

将输入张量的 batch 维度按 block 因子分解并重排到空间维度,随后根据 crops 参数对输出空间范围进行裁剪。

  • 输入形状: [batch, height, width, channel]

  • block_size[block_h, block_w]

  • crops[top, bottom, left, right]

输入:
  • input - 输入数据地址。

  • input_shape - 输入形状,格式为 [batch, height, width, channel]

  • block_size - 分块因子,格式为 [block_h, block_w]

  • crops - 裁剪参数,格式为 [top, bottom, left, right]

  • core_mask(int, 可选) - 核掩码(仅适用于共享存储版本)。

输出:
  • output - 输出数据地址。

支持平台:

FT78NE MT7004

备注

  • FT78NE 支持的数据类型: fp32、fp64、cplx64、cplx128、int16、int8、int32。

  • MT7004 支持的数据类型: fp32、fp16、cplx64、int16、int32。
