GPTQ是一种针对Transformer模型的量化方法。它将模型的权重和激活值从浮点数转换为低精度的定点数,从而减少模型的存储空间和计算量。GPTQ量化版本可以在保证模型性能的前提下,显著提高模型在移动设备或嵌入式设备上的运行速度。 四、Mixtral MoE与GPTQ在VLLM测试中的实战应用 为了验证Mixtral MoE模型与GPTQ量化版本在...
we currently find two workarounds use gptq_marlin, which is available for Ampere and later cards. change the number on this line from 50 to 0 and install from the modified source code. it may affect speed on short sequences though. https://github.com/QwenLM/Qwen2.5/issues/1103#issue...

Currently, we support "awq", "gptq" and "squeezellm". If None, we first check the `quantization_config` attribute in the model config file. If that is None, we assume the model weights are not quantized and use `dtype` to determine the data type of the weights. revision: The specif...
用LLama Factory的微调并导出大模型时.由于很多模块如之间的依赖关系复杂很容易造成版本冲突,主要涉及到cuda/pytorch/python/auto-gptq/vllm的版本选择.我在AutoDL上经实验了(高,低)两种组合能正常运行LLama Factory,以下是详细说明. 一.硬件配置 采用租用云算力服务器方式:由于是基于大于1B的大模型需要硬件配置...

本仓库是基于vLLM(版本0.2.2)进行修改的一个分支,主要为了支持Qwen系列大语言模型的GPTQ量化推理。 This repo is a fork of vLLM(Version: 0.2.2), which supports the GPTQ model inference ofQwen large language models. 新增功能 该版本vLLM跟官方0.22版本的主要区别在于增加GPTQ int4量化模型支持。我们在...
