.. _cn_api_tensor_cn_chunk: chunk ------------------------------- .. py:function:: paddle.chunk(x, chunks, axis=0, name=None) 该OP将输入Tensor分割成多个子Tensor。 **参数**: - **x** (Tensor) - 输入变量,数据类型为bool, float16, float32,float64,int32,int64的多维Tensor。 - **chunks** (int) - ``chunks`` 是一个整数,表示将输入Tensor划分成多少个相同大小的子Tensor。 - **axis** (int|Tensor,可选) - 整数或者形状为[1]的Tensor,数据类型为int32或int64。表示需要分割的维度。如果 ``axis < 0`` ,则划分的维度为 ``rank(x) + axis`` 。默认值为0。 - **name** (str,可选) – 具体用法请参见 :ref:`api_guide_Name` ,一般无需设置,默认值为None。 返回:分割后的Tensor列表。 **代码示例** .. code-block:: python import numpy as np import paddle paddle.disable_static() # x is a Tensor which shape is [3, 9, 5] x_np = np.random.random([3, 9, 5]).astype("int32") x = paddle.to_tensor(x_np) out0, out1, out2 = paddle.chunk(x, chunks=3, axis=1) # out0.shape [3, 3, 5] # out1.shape [3, 3, 5] # out2.shape [3, 3, 5] # axis is negative, the real axis is (rank(x) + axis) which real # value is 1. out0, out1, out2 = paddle.chunk(x, chunks=3, axis=-2) # out0.shape [3, 3, 5] # out1.shape [3, 3, 5] # out2.shape [3, 3, 5]
