腾讯混元hunyuan3d生成模型,本地搭建和使用

腾讯终于出了一个比较厉害的AI,可以根据文本或者图片生成3d模型,下面是它的基本逻辑

一. 话不多说,我们直接上本地部署的详细步骤

1. 将仓库拉到本地

• hunyuan3D 仓库 地址

mkdir Hunyuan3D-1
git clone https://github.com/Tencent/Hunyuan3D-1.git

2. 下载2个模型, 注意这里推荐 先使用conda创建环境后在安装modelscope进行下载模型

• 1. AI-ModelScope/Hunyuan3D-1
• 2. AI-ModelScope/HunyuanDiT-v1.1-Diffusers-Distilled

2.1 关于第一个模型我们要在 Hunyuan3D-1 中创建文件夹 weights,然后将下载的模型都放进去。

mkdir weights
这里推荐使用模型库来下载,而不是gitpip install modelscopemodelscope download --model AI-ModelScope/Hunyuan3D-1 --local_dir ./weights

2.2 下载第二个模型Hunyuan3D-1\weights 下面新建文件夹 hunyuanDiT ，然后将下载下来的模型文件都放进去。

mkdir ./weights/hunyuanDiT
这里推荐使用模型库来下载,而不是gitpip install modelscopemodelscope download --model AI-ModelScope/HunyuanDiT-v1.1-Diffusers-Distilled --local_dir  ./weights/hunyuanDiT

二. 创建虚拟环境

conda create -n hunyuan3d python=3.10
conda activate hunyuan3d

我的 cuda 是 12.1 把那本，使用下面命令安装 torch 等相关库

pip install torch==2.2.0 torchvision==0.17.0 torchaudio==2.2.0 --index-url https://download.pytorch.org/whl/cu121

进入 D:\Hunyuan3D-1 目录下面，修改 requirements.txt 文件如下，安装下面的库

diffusers==0.31.0
numpy==1.26.4
transformers==4.46.2
rembg==2.0.59
tqdm==4.67.0
omegaconf==2.3.0
matplotlib==3.9.2
opencv-python==4.10.0.84
imageio==2.36.0
jaxtyping==0.2.34
einops==0.8.0
sentencepiece==0.2.0
accelerate==1.1.1
trimesh==4.5.2
PyMCubes==0.1.6
xatlas==0.0.9
libigl==2.5.1
# pytorch3d==0.7.6
git+https://github.com/facebookresearch/pytorch3d@stable
# nvdiffrast==0.3.3
git+https://github.com/NVlabs/nvdiffrast
open3d==0.18.0
ninja==1.11.1.1

执行下面的命令

pip install -r requirements.txt

文生3D模型测试

在 D:\Hunyuan3D-1 目录下面使用下面的命令进行生成。

python main.py  --text_prompt "一颗红色的柳树"  --save_folder ./outputs/liushu/  --max_faces_num 90000  --do_texture_mapping  --do_render

运行报错: 1. dust3r的问题

cd third_party
git clone --recursive https://github.com/naver/dust3r.git去下载这个模型然后放到third_party/weights中
https://download.europe.naverlabs.com/ComputerVision/DUSt3R/DUSt3R_ViTLarge_BaseDecoder_512_dpt.pthcd ../third_party/weights

运行报错2. ModuleNotFoundError: No module named ‘roma’

pip install roma

然后再次运行, 出现下面的命令

(hunyuan3d) PS D:\Hunyuan3D-1>  python main.py  --text_prompt "一颗红色的柳树"  --save_folder ./outputs/liushu/  --max_faces_num 90000  --do_texture_mapping  --do_render

### 点击 mesh.obj 进行查看，是不是很牛X，可以自动生成一幢楼的 3d 模型。

生成其他案例

使用 Gradio

我们准备了两个版本的多视图生成，std 和 lite。

std模式

# std 
python3 app.py
python3 app.py --save_memory

lite 模式

python3 app.py --use_lite
python3 app.py --use_lite --save_memory

然后可以通过 http://0.0.0.0:8080 访问演示。需要注意的是，这里的 0.0.0.0 需要是你的服务器 IP 的 X.X.X.X。
