除了下面俩直接能改的，还有 append_attention 申明为自定义算子的这部分，Outputs 也要改一下
因为咱 append_attention 不是不需要输出 qkv_out 了嘛，所以删掉它
PD_BUILD_STATIC_OP(append_attention)
.Inputs({"qkv",
......
.Outputs({"fmha_out", "qkv_out", "key_cache_out", "value_cache_out"}) # <--- 这一行
.SetInplaceMap({{"key_cache", "key_cache_out"},
改成
.Outputs({"fmha_out", "key_cache_out", "value_cache_out"})
PS: 自定义算子的注册出问题总是直接抛出这种异常，后续主框架也要添加更多上下文信息
terminate called after throwing an instance of 'std:bad_array_new_length'
what(): std: ： bad_array_new_length

这里把 rms_norm_eps 的顺序往前移动一下
