.. _cn_api_paddle_tensor_t: t ------------------------------- .. py:function:: paddle.tensor.t(input, name=None) 该OP对小于等于2维的Tensor进行数据转置。0维和1维Tensor返回本身,2维Tensor等价于perm设置为0,1的 :ref:`cn_api_fluid_layers_transpose` 函数。 参数: - **input** (Variable) - 输入:N维(N<=2)Tensor,可选的数据类型为float16, float32, float64, int32, int64。 - **name** (str, 可选)- 该参数供开发人员打印调试信息时使用,具体用法请参见 :ref:`api_guide_Name` ,默认值为None 返回: N维Tensor 返回类型:Variable **示例**: .. code-block:: python # 例1 (0-D tensor) x = tensor([0.79]) paddle.t(x) = tensor([0.79]) # 例2 (1-D tensor) x = tensor([0.79, 0.84, 0.32]) paddle.t(x) = tensor([0.79, 0.84, 0.32]) # 例3 (2-D tensor) x = tensor([0.79, 0.84, 0.32], [0.64, 0.14, 0.57]) paddle.t(x) = tensor([0.79, 0.64], [0.84, 0.14], [0.32, 0.57]) **代码示例**: .. code-block:: python import paddle import paddle.fluid as fluid x = fluid.data(name='x', shape=[2, 3], dtype='float32') x_transposed = paddle.t(x) # paddle.t 等价于 paddle.tensor.t print(x_transposed.shape) #(3L, 2L)
