There was a problem hiding this comment.
If the custom model has no rope parameters (i.e. it is {}), we will get triggered by the original issue of evaluting to True, no?

You're right that if rope_parameters is explicitly set to {} we'll still get here. But if rope_parameters is unset, it will remain None and this method will exit early with a warning

set(rope_parameters.keys()).issubset(self.layer_types)will evaluate toTrueifrope_parametersis an emptydict.This is a problem if
standardise_rope_paramsis called on a config for a model which do not have RoPE because it will triggerCase 2. This method might be called on models which do not have RoPE in third party libraries (e.g. vLLM) in order to "upgrade" configs of custom models they use.This PR makes
standardise_rope_paramsharmless to call on configs with no RoPE at all.
