oneflow.Tensor.new_zeros

Tensor.new_zeros(size=None, dtype=None, device=None, placement=None, sbp=None, requires_grad=False)Tensor

Returns a Tensor of size size filled with 0. By default, the returned Tensor has the same oneflow.dtype, oneflow.device or oneflow.placement and oneflow.sbp 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 numpy as np
>>> import oneflow as flow

>>> x = flow.Tensor(np.ones((1, 2, 3)))
>>> y = x.new_zeros((2, 2))
>>> y
tensor([[0., 0.],
        [0., 0.]], dtype=oneflow.float32)
