Overview

This is a duplicate of ashawkey/imagedream-ipmv-diffusers.

It is hosted here for the purpose of persistence and reproducibility for the ML for 3D course.

Usage

This project can be used from other projects as follows.

import torch
from diffusers import DiffusionPipeline

pipeline = DiffusionPipeline.from_pretrained(
    "ashawkey/mvdream-sd2.1-diffusers",
    custom_pipeline="dylanebert/multi_view_diffusion",
    torch_dtype=torch.float16,
    trust_remote_code=True,
)

MVDream-diffusers

A unified diffusers implementation of MVDream and ImageDream.

We provide converted fp16 weights on huggingface:

Install

# dependency
pip install -r requirements.txt

# xformers is required! please refer to https://github.com/facebookresearch/xformers
pip install ninja
pip install -v -U git+https://github.com/facebookresearch/xformers.git@main#egg=xformers

Usage

python run_mvdream.py "a cute owl"
python run_imagedream.py data/anya_rgba.png

Convert weights

MVDream:

# download original ckpt (we only support the SD 2.1 version)
mkdir models
cd models
wget https://huggingface.co/MVDream/MVDream/resolve/main/sd-v2.1-base-4view.pt
wget https://raw.githubusercontent.com/bytedance/MVDream/main/mvdream/configs/sd-v2-base.yaml
cd ..

# convert
python convert_mvdream_to_diffusers.py --checkpoint_path models/sd-v2.1-base-4view.pt --dump_path ./weights_mvdream --original_config_file models/sd-v2-base.yaml --half --to_safetensors --test

ImageDream:

# download original ckpt (we only support the pixel-controller version)
cd models
wget https://huggingface.co/Peng-Wang/ImageDream/resolve/main/sd-v2.1-base-4view-ipmv.pt
wget https://raw.githubusercontent.com/bytedance/ImageDream/main/extern/ImageDream/imagedream/configs/sd_v2_base_ipmv.yaml
cd ..

# convert
python convert_mvdream_to_diffusers.py --checkpoint_path models/sd-v2.1-base-4view-ipmv.pt --dump_path ./weights_imagedream --original_config_file models/sd_v2_base_ipmv.yaml --half --to_safetensors --test
