flip¶

dragon.vm.torch.flip(
  input,
  dims
)[source]¶

Reverse elements along the given dimension.

dims could be negative:

x = torch.tensor([[1, 2, 3], [4, 5, 6]])

# A negative dimension is the last-k dimension
print(torch.flip(x, dims=1))  # [[3, 2, 1], [6, 5, 4]]
print(torch.flip(x, dims=-1))  # Equivalent

# Also, dimension could be a sequence of integers
print(torch.flip(x, dims=(0, 1)))  # [[6, 5, 4], [3, 2, 1]]

Parameters:

• input (dragon.vm.torch.Tensor) – The input tensor.
• dims (Union[int, Sequence[int]]) – The dimension to reverse.

Returns:

dragon.vm.torch.Tensor – The output tensor.
