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
