numpy.from_dlpack — NumPy v2.6.dev0 Manual

numpy.from_dlpack(x, /, *, device=None, copy=None)

#

Create a NumPy array from an object implementing the __dlpack__ protocol. Generally, the returned NumPy array is a view of the input object. See

[1]

and

[2]

for more details.

Parameters:xobjectA Python object that implements the __dlpack__ and __dlpack_device__ methods.

devicedevice, optionalDevice on which to place the created array. Default: None. Must be "cpu" if passed which may allow importing an array that is not already CPU available.

copybool, optionalBoolean indicating whether or not to copy the input. If True, the copy will be made. If False, the function will never copy, and will raise BufferError in case a copy is deemed necessary. Passing it requests a copy from the exporter who may or may not implement the capability. If None, the function will reuse the existing memory buffer if possible and copy otherwise. Default: None.

Returns:outndarrayReferences

Examples

>>> importtorch>>> x=torch.arange(10)>>> # create a view of the torch tensor "x" in NumPy>>> y=np.from_dlpack(x)
