Flux 文生图模型，是 Black Forest Labs 最近发布的模型，图片生成清晰度很高，模型可以在 ModelScope 上进行下载，本文将在本地环境中部署 Flex。使用环境如下
- 2080 TI 22G
- Ubuntu 22
- Amd R7 2700 / 128G
启动 Model Scope 容器
ModelScope 1.16 版本
docker run --rm --runtime=nvidia --shm-size=32g --gpus all -p 8890:8888 -p 8891-8895:8891-8895 \
-v /opt/modelscope/models:/mnt/workspace/.cache \
-v /opt/modelscope/notebook:/notebook \-it registry.cn-beijing.aliyuncs.com/modelscope-repo/modelscope:ubuntu22.04-cuda12.1.0-py310-torch2.3.0-tf2.16.1-1.16.0 /bin/bash
通过 Notebook 启动 ComfyUI
安装 ComfyUI
from pathlib import PathOPTIONS = {}UPDATE_COMFY_UI = True #@param {type:"boolean"}
WORKSPACE = 'ComfyUI'
OPTIONS['UPDATE_COMFY_UI'] = UPDATE_COMFY_UIWORKSPACE = "./ComfyUI"![ ! -d $WORKSPACE ] && echo -= Initial setup ComfyUI =- && git clone https://github.com/comfyanonymous/ComfyUI
%cd $WORKSPACEif OPTIONS['UPDATE_COMFY_UI']:!echo -= Updating ComfyUI =-!git pull!echo -= Install dependencies =-
!pip install -r requirements.txt
