.. py:function:: paddle.fluid.Tensor
``LoDTensor`` 的别名
Tensor用于表示多维张量,可以通过 ``np.array(tensor)`` 方法转换为numpy.ndarray。
**示例代码**
.. code-block:: python
import paddle.fluid as fluid
t = fluid.Tensor()
.. py:method:: set(*args, **kwargs)
该接口根据输入的numpy array和设备place,设置Tensor的数据。

参数:
- **array** (numpy.ndarray) - 要设置的numpy array,支持的数据类型为bool, float32, float64, int8, int32, int64, uint8, uint16。
- **place** (CPUPlace|CUDAPlace|CUDAPinnedPlace) - 要设置的Tensor所在的设备。
返回:无。
**示例代码**
.. code-block:: python
import paddle.fluid as fluid
import numpy as np
t = fluid.Tensor()
t.set(np.ndarray([5, 30]), fluid.CPUPlace())
.. py:method:: shape(self: paddle.fluid.core_avx.Tensor) → List[int]
该接口返回Tensor的shape。
返回:Tensor的shape。
返回类型:List[int] 。
**示例代码**
.. code-block:: python
import paddle.fluid as fluid
import numpy as np
t = fluid.Tensor()
t.set(np.ndarray([5, 30]), fluid.CPUPlace())
print(t.shape()) # [5, 30]
