slice¶
dragon.
slice
(
inputs,
starts,
sizes,
**kwargs
)[source]¶Select the elements according to the given sections.
Each section should be hinted by a pair of
[start, start + size)
:x = dragon.constant([[[0, 1, 2], [3, 4, 5]]]) print(dragon.slice(x, [0, 1, 2], [1, 1, 1])) # [[[5]]] print(x[0:1, 1:2:, 2:3]) # Equivalent
sizes
accepts value-1
or0
:x = dragon.constant([[[0, 1, 2], [3, 4, 5]]]) # Set ``0`` to squeeze dimensions with size 1 print(dragon.slice(x, [0, 1, 2], [0, 0, 0])) # 5 # Set ``-1`` to take all the remained elements print(dragon.slice(x, [0, 0, 0], [-1, -1, -1])) # [[[0, 1, 2], [3, 4, 5]]]
- Parameters:
- inputs (dragon.Tensor) – The input tensor.
- starts (Union[Sequence[int], dragon.Tensor]) – The start location for each dimension.
- sizes (Union[Sequence[int], dragon.Tensor]) – The number of elements sliced from start.
- Returns:
dragon.Tensor – The output tensor.
