System Info

您好，感谢这份开源框架，帮助我们在工作中解决了很多的问题。首先以不是报错，而是warning，内容为：Sliding Window Attention is enabled but not implemented for sequence_parallel_attention; unexpected results may be encountered.

warning的地址发生在transformers model qwen2 的里面，请问这个warning是否影响最终的效果呢？

Reproduction

warning地址为：Library/Python/3.9/lib/python/site-packages/transformers/models/qwen2/modeling_qwen2.py

Expected behavior

    if config.sliding_window and config._attn_implementation != "flash_attention_2":
        logger.warning_once(
            f"Sliding Window Attention is enabled but not implemented for `{config._attn_implementation}`; "
            "unexpected results may be encountered."
        )  这个地方的代码是这么写的。
