I'm running into an issue where the first time I call
apply_repeat_penalty
, it takes a very long time (in excess of 6 seconds). It seems to be coming from theTensor::to_vec1d
call to move the logits into aVec<f32>
. It seems like a simple copy like this would be very fast.It was suggested on Discord that this slowness might be due to some other async stuff happening in Metal, maybe the compilation of the kernels on first load.
This PR precompiles the kernels at build time instead of on every run. Unfortunately, it doesn't seem to solve my problem but it might be useful for other reasons.
