Megatron performs batch matrix multiplications in a couple places, such as within self attention and in SwiGLU, that Llama performs separately.

原始的Llama模型,只堆叠layer层数然后做self-attention操作获得编码之后的特征,没有在模型最顶层加一些自回归头等,因此可以直观地理解成一个Decoder,下面是其Huggingface源码(https://github.com/huggingface/transformers/blob/v4.37.2/src/transformers/models/llama/modeling_llama.py#L939): classLlamaModel(LlamaPreTra...
