LMDeploy 量化部署实践闯关任务

环境配置

conda create -n lmdeploy  python=3.10 -y
conda activate lmdeploy
conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=12.1 -c pytorch -c nvidia -y
pip install timm==1.0.8 openai==1.40.3 lmdeploy[all]==0.5.3pip install datasets==2.19.2

创建文件夹并设置开发机共享目录的软链接。

mkdir /root/models
ln -s /root/share/new_models/Shanghai_AI_Laboratory/internlm2_5-7b-chat /root/models
ln -s /root/share/new_models/Shanghai_AI_Laboratory/internlm2_5-1_8b-chat /root/models
ln -s /root/share/new_models/OpenGVLab/InternVL2-26B /root/models

启动InternLM2_5-1_8b-chat

lmdeploy chat /root/models/internlm2_5-1_8b-chat

API部署

lmdeploy serve api_server \/root/models/internlm2_5-1_8b-chat \--model-format hf \--quant-policy 0 \--server-name 0.0.0.0 \--server-port 23333 \--tp 1

以命令行形式连接API服务器
关闭http://127.0.0.1:23333网页，但保持终端和本地窗口不动，新建一个终端。

以Gradio网页形式连接API服务器

lmdeploy serve gradio http://localhost:23333 \--server-name 0.0.0.0 \--server-port 6006

W4A16 量化+ KV cache+KV cache 量化

lmdeploy serve api_server \/root/models/internlm2_5-1_8b-chat-w4a16-4bit/ \--model-format awq \--quant-policy 4 \--cache-max-entry-count 0.4\--server-name 0.0.0.0 \--server-port 23333 \--tp 1

原模型

量化后

量化后做kv cache

lmdeploy serve api_server \/root/models/internlm2_5-1_8b-chat-w4a16-4bit/ \--model-format awq \--quant-policy 4 \--cache-max-entry-count 0.4\--server-name 0.0.0.0 \--server-port 23333 \--tp 1

Function call

conda activate lmdeploy
lmdeploy serve api_server \/root/models/internlm2_5-7b-chat \--model-format hf \--quant-policy 0 \--server-name 0.0.0.0 \--server-port 23333 \--tp 1
