from_dlpack¶

paddle.utils.dlpack. from_dlpack ( dlpack ) [source]

Decodes a DLPack to a tensor.

Parameters

dlpack (PyCapsule) – a PyCapsule object with the dltensor.

Returns

out (Tensor), a tensor decoded from DLPack. One thing to be noted, if we get

an input dltensor with data type as bool, we return the decoded tensor as uint8.

Examples

>>> import paddle
>>> # x is a tensor with shape [2, 4]
>>> x = paddle.to_tensor([[0.2, 0.3, 0.5, 0.9],
...                       [0.1, 0.2, 0.6, 0.7]])
>>> dlpack = paddle.utils.dlpack.to_dlpack(x)
>>> x = paddle.utils.dlpack.from_dlpack(dlpack)
>>> print(x)
Tensor(shape=[2, 4], dtype=float32, place=Place(cpu), stop_gradient=True,
       [[0.20000000, 0.30000001, 0.50000000, 0.89999998],
        [0.10000000, 0.20000000, 0.60000002, 0.69999999]])
