Candle Extensions

An extension library to Candle that provides PyTorch functions not currently available in Candle

 use candle_ext::{
     candle::{ D, DType, Device, Result, Tensor},
     TensorExt, F,
 };

 fn main() -> Result<()> {
     let device = Device::Cpu;
     let q = Tensor::randn(0., 1., (3, 3, 2, 4), &device)?;
     let k = Tensor::randn(0., 1., (1, 3, 3, 4), &device)?;
     let v = Tensor::randn(0., 1., (1, 3, 3, 4), &device)?;
     let m = Tensor::ones((q.dim(D::Minus2)?, k.dim(D::Minus2)?), DType::U8, &device)?.tril(0)?;

     let o = F::scaled_dot_product_attention(&q, &k, &v, Some(&m), None, None, None)?;

     Ok(())
 }
