当使用大语言模型(LLM)进行批量推理(Batch Inference)时,即使关闭随机采样(sampling=False),结果仍可能与单例推理(batch_size=1)不同,核心原因可分为随机性相关因素和确定性解码中的系统性偏差两类: 随机性相关因素(可通过参数控制) 温度参数(Temperature) :强制选择概率最高的token(贪心解码),结果高
Batch inference example notebooks using Python The following example notebook creates a provisioned throughput endpoint and runs batch LLM inference using Python and the Meta Llama 3.1 70B model. It also has guidance on benchmarking your batch inference workload and creating a provisioned throughput ...
llms batch推理代码 文心快码BaiduComate LLM(大型语言模型)的批量推理(batch inference)是提高模型推理效率和吞吐量的重要手段。下面我将详细解释如何进行LLM的批量推理,并附上相应的代码片段。 1. 准备推理数据 首先,需要将数据整理为适合批量推理的格式,如CSV或JSONL。这里以JSONL格式为例,每个样本是一个JSON对象...
Batch Decoding/Inference of LLMs will cause different outputs with different batch size?! 并且VLLM等框架都有这个问题,不完全是精度和溢出的问题 行为表现 测试中可以发现,即使是在推理阶段,不是在训练阶段,对于多模态大模型VLLM,如果推理时候为了加速推理,不是一条一条数据让模型推,而是一次推理batch_size>1...

vLLM 提供了两类推理的实现,一类是 offline inference,类似于 HF pipeline 的 batch 推理接口,用于离线批量的推理生成;一类是和 openai api 类似的实时在线推理,用于服务端接收并发推理请求的应用部署,其本身也可以通过命令行拉起一个 web 服务端进行部署。
