Description
Previously, GQA incorrectly enforced rotary cos and sin cache to be of sequence length equal to present sequence length. Now it enforces that it be greater than or equal to present sequence length since to match Rotary Embedding Op it should be of max_sequence_length
Motivation and Context
Fixes issue with fusing Rotary Embedding and GQA for certain models which prefer this optimization.
