Slice

Slice

Extracts a contiguous slice from a tensor along specified dimensions.

Parameters:

  • dim: Dimension to slice along
  • start: Starting index (inclusive)
  • end: Ending index (exclusive, use -1 for end)

Shape Contract:

  • Input: [*shape_in] tensor to slice
  • Output: [*shape_out] sliced tensor (smaller along dim)

Notes:

  • No learnable parameters (pure structural operation)
  • Supports negative indexing (Python-style)
  • end=-1 means slice to the end
  • Commonly used to extract specific positions or ranges
  • Memory efficient (view operation when possible)
