When does this happen?

IF Using V1 engine with flash_attn or triton_attn backends causes NotImplementedError because these backends lack the `get_state_cls` method.

How others solved it

THEN Temporarily disable the V1 engine by setting the environment variable `VLLM_USE_V1=0`, or switch to a different attention backend that supports V1. The vLLM development team is expected to add the missing `get_state_cls` implementation in a future release.
