oneflow.Tensor.new_empty¶
-
Tensor.
new_empty
(*size, dtype=None, device=None, placement=None, sbp=None, requires_grad=False) → Tensor¶ Returns a Tensor of size
size
filled with uninitialized data. By default, the returned Tensor has the sameflow.dtype
andflow.device
as this tensor.- Parameters
size (int...) – a list, tuple, or flow.Size of integers defining the shape of the output tensor.
dtype (flow.dtype, optional) – the desired type of returned tensor. Default: if None, same flow.dtype as this tensor.
device (flow.device, optional) – the desired device of returned tensor. Default: if None, same flow.device as this tensor.
placement (flow.placement, optional) – the desired placement of returned global tensor. Default: if None, the returned tensor is local one using the argument device.
sbp (flow.sbp.sbp or tuple of flow.sbp.sbp, optional) – the desired sbp descriptor of returned global tensor. Default: if None, the returned tensor is local one using the argument device.
requires_grad (bool, optional) – If autograd should record operations on the returned tensor. Default: False.
For example:
>>> import oneflow as flow >>> x = flow.ones(()) >>> y = x.new_empty((2, 2)) >>> y.shape oneflow.Size([2, 2])
