Implementations§

Source §

impl RopeCache

Source

pub fn new( head_dim: usize, max_seq: usize, theta: f64, device: &Device, ) -> Result<Self>

Source

pub fn apply(&self, x: &Tensor, start_pos: usize) -> Result<Tensor>

Apply RoPE to x with shape [b, n_heads, seq, head_dim].

Llama rotation: x * cos + rotate_half(x) * sin rotate_half(x) = cat([-x[…, half:], x[…, :half]], dim=-1)
