旅游型网站建设用个人电脑做网站的步骤

一、下载GGUF模型

1. 创建目录

mkdir DeepSeek-R1-GGUF

2. 魔塔下载 DeepSeek-R1-Q4_K_M

https://www.modelscope.cn/models/unsloth/DeepSeek-R1-GGUF

3. 安装显卡驱动和cuda

wget https://developer.download.nvidia.com/compute/cuda/12.6.0/local_installers/cuda_12.6.0_560.28.03_linux.run
sudo sh cuda_12.6.0_560.28.03_linux.run

4. 显卡 NVIDIA GeForce RTX 4090

NVIDIA-SMI 560.35.05 
CUDA Version: 12.6  

二、安装ktransformers

1. 安装依赖

sudo apt-get install git

2. 安装uv工具链

curl -LsSf https://astral.sh/uv/install.sh | sh
source $HOME/.local/bin/env
which uv
which uvx

3. 下载源码

git clone https://github.com/kvcache-ai/ktransformers.git
cd ktransformers
git checkout 94ab2de
git rev-parse --short HEAD # 应显示 94ab2de

4. 创建python虚拟环境

# uv venv ./venv --python 3.11 --python-preference=only-managed
Using CPython 3.11.11
Creating virtual environment at: ./venv
Activate with: source venv/bin/activate

三、编译ktransformers

apt-get install build-essential cmake

source venv/bin/activate
uv pip install -r requirements-local_chat.txt
uv pip install setuptools wheel packaging

# uv pip install setuptools wheel packaging

This may lead to degraded performance.If the cache and target directories are on different filesystems, hardlinking may not be supported.If this is intentional, set `export UV_LINK_MODE=copy` or use `--link-mode=copy` to suppress this warning.

系统的物理CPU核心数量
export MAX_JOBS=72
export CMAKE_BUILD_PARALLEL_LEVEL=72

# 安装flash_attn
uv pip install flash_attn --no-build-isolation
export UV_LINK_MODE=copy
uv pip install flash_attn --no-build-isolation

export USE_NUMA=1
git submodule init
git submodule update
KTRANSFORMERS_FORCE_BUILD=TRUE uv pip install . --no-build-isolation

四、运行ktransformers

PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True python3 ktransformers/server/main.py \--gguf_path /DeepSeek-R1-GGUF/DeepSeek-R1-Q4_K_M/ \--model_path deepseek-ai/DeepSeek-R1 \--model_name unsloth/DeepSeek-R1-GGUF \--cpu_infer 16 \--max_new_tokens 8192 \--cache_lens 32768 \--total_context 32768 \--cache_q4 true \--temperature 0.6 \--top_p 0.95 \--optimize_config_path ktransformers/optimize/optimize_rules/DeepSeek-V3-Chat.yaml \--force_think \--use_cuda_graph \--host 0.0.0.0 \--port 8080

1. 后台运行

nohup env PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True python3 ktransformers/server/main.py \--gguf_path /DeepSeek-R1-GGUF/DeepSeek-R1-Q4_K_M/ \--model_path deepseek-ai/DeepSeek-R1 \--model_name unsloth/DeepSeek-R1-GGUF \--cpu_infer 16 \--max_new_tokens 8192 \--cache_lens 32768 \--total_context 32768 \--cache_q4 true \--temperature 0.6 \--top_p 0.95 \--optimize_config_path ktransformers/optimize/optimize_rules/DeepSeek-V3-Chat.yaml \--force_think \--use_cuda_graph \--host 0.0.0.0 \--port 8080 >> server.log 2>&1 &

2. API 测试

curl http://IP:8080/v1/chat/completions \-H "Content-Type: application/json" \-d '{"model": "DeepSeek-R1","messages": [{"role": "user", "content": "你是谁!"}]}'

五、open-webui 集成

1. 安装 open-webui

mkdir open-webui
cd open-webui
uv venv ./venv --python 3.11
source venv/bin/activate
uv pip install open-webui

2. 运行脚本go.sh

#!/usr/bin/env bashsource venv/bin/activate# open-webui 不原生支持HOST和PORT环境变量，需手动传递参数
# https://docs.openwebui.com/getting-started/env-configuration/#port
# 若open-webui运行异常，可执行`rm -rf ./data`清除数据后重启服务并清理浏览器缓存export DATA_DIR="$(pwd)/data"
export ENABLE_OLLAMA_API=False
export ENABLE_OPENAI_API=True
export OPENAI_API_KEY="dont_change_this_cuz_openai_is_the_mcdonalds_of_ai"
export OPENAI_API_BASE_URL="http://IP:8080/v1" # <--- 需与ktransformers/llama.cpp的API配置匹配
#export DEFAULT_MODELS="openai/foo/bar" # <--- 保留注释，此参数用于`litellm`接入
export WEBUI_AUTH=False
export DEFAULT_USER_ROLE="admin"
export HOST=0.0.0.0
export PORT=3000 # <--- open-webui网页服务端口open-webui serve \--host $HOST \--port $PORT# 在浏览器中访问显示的URL:端口

3. 启动过程很慢，监听端口 3000 运行后可以访问web界面

netstat -netlp
