简介： 应近日来诸多社区开发者的学习诉求，特为大家推出一期 FLUX.1-LoRA/IP-adapter+ComfyUI +“顶流”IP「黑神话：悟空」的模型推理实战教程，玩转一把AI悟空生图 👀

引言

Black Forest Labs 的新文本生成图像模型FLUX.1自推出以来就引起了开源社区很大的轰动，成为新一代的文生图模型的旗舰。虽然开源时间不久，但围绕Flux.1的社区开源生态发展迅猛，包括量化版本，GGUF版本，以及配套的Controlnet模型、LoRA模型均在各大开源平台上线，而配合各个模型的使用，对应的ComfyUI工作流也在蓬勃发展。

PS：本教程只限社区学习使用，不可投入商业用途。

最佳实践

环境配置和安装：

python 3.10及以上版本
pytorch 1.12及以上版本，推荐2.0及以上版本
建议使用CUDA 11.4及以上

本文在魔搭社区免费提供的GPU免费算力上体验：

开发者也可以使用modelscope的官方镜像，在云端或自有的设备上体验。

GPU环境镜像(python3.10)：
