Additional information
When manually applying YaRN (or changing the scaling)
n_ctx_trainis left in original state, causingserverto cap context to old size.To work around this you previously had to do fiddly things like
--override-kv <insert architecture here>.context_length=int:<new context length>.Now you can simply specify f.ex.
--rope-scaling yarn --rope-scale 4andn_ctx_trainwill be automatically re-adjusted and YaRN then works as expected.Requirements
