DeepSpeed-MII可以在只有1个副本的情况下在多个GPU上进行推理吗?

我有两个节点,每个节点都有一个16GB的GPU。我想在这两个节点上运行llama-2-13b-hf模型,每个节点有一个副本。
查看/job/hostfile:

deepspeed-mii-inference-worker-0 slots=1
deepspeed-mii-inference-worker-1 slots=1

服务器代码

import mii

client = mii.serve(
    "/data/Llama-2-13b-hf/",
    deployment_name="llama2-deployment",
    enable_restful_api=True,
    restful_api_port=28080,
    tensor_parallel=2,
    replica_num=1
)

错误:

你好@gujingit,我们目前不支持在节点之间拆分模型,只支持在单个节点上的GPU之间拆分,然后在不同的节点上拥有副本。

@mrwyattii 你好~ DeepSpeed-MII是否支持单个节点上的多个副本?例如,我有一个带有8个A100 GPU的节点,我将tensor_parallel设置为4,replica_num设置为2。我发现每次只有4个GPU在工作,剩下的4个GPU只是等待。有点奇怪!
