oneflow.amin

oneflow.amin(input, dim, keepdim=False)Tensor

Returns the minimum value of each slice of the input tensor in the given dimension(s) dim.

If keepdim is True, the output tensor is of the same size as input except in the dimension(s) dim where it is of size 1. Otherwise, dim is squeezed (see oneflow.squeeze()), resulting in the output tensor having 1 (or len(dim)) fewer dimension(s).

This function is equivalent to PyTorch’s amin function. The documentation is referenced from: https://pytorch.org/docs/1.10/generated/torch.amin.html.

Parameters
  • input (oneflow.Tensor) – the input Tensor.

  • dim (int, Tuple[int]) – the dimension or dimensions to reduce.

  • keepdim (bool) – whether the output tensor has dim retained or not.

Example:

>>> import oneflow as flow

>>> x = flow.tensor([[[0,1],[2,3]],[[4,5],[6,7]]])
>>> flow.amin(x, 1)
tensor([[0, 1],
        [4, 5]], dtype=oneflow.int64)
>>> flow.amin(x, 0)
tensor([[0, 1],
        [2, 3]], dtype=oneflow.int64)
>>> flow.amin(x)
tensor(0, dtype=oneflow.int64)
>>> flow.amin(x, 0, True)
tensor([[[0, 1],
         [2, 3]]], dtype=oneflow.int64)
