Zero-1-to-3: Zero-shot One Image to 3D Object

A HuggingFace Diffusers implementation of Zero123.

Merged into Diffusers Repo here.

Updates

Usage

Pytorch 2.0 for faster training and inference.

conda create -f environment.yml

or

conda create -n zero123-hf python=3.9
conda activate zero123-hf
pip install -r requirements.txt

Install xformer properly to enable efficient transformers.

conda install xformers -c xformers
# from source
pip install -v -U git+https://github.com/facebookresearch/xformers.git@main#egg=xformers

Run diffusers pipeline demo:

python test_zero1to3.py

Run our gradio demo for novel view synthesis:

python gradio_new.py

Training

Download Zero123's Objaverse Renderings data:

wget https://tri-ml-public.s3.amazonaws.com/datasets/views_release.tar.gz

Configure accelerator by

accelerate config

Launch training:

Follow Original Zero123, fp32, gradient checkpointing, and EMA are turned on.

accelerate launch train_zero1to3.py \
--train_data_dir /data/zero123/views_release \
--pretrained_model_name_or_path lambdalabs/sd-image-variations-diffusers \
--train_batch_size 192 \
--dataloader_num_workers 16 \
--output_dir logs \
--use_ema \
--gradient_checkpointing \
--mixed_precision no

While bf16/fp16 is also supported by running below

accelerate launch train_zero1to3.py \
--train_data_dir /data/zero123/views_release \
--pretrained_model_name_or_path lambdalabs/sd-image-variations-diffusers \
--train_batch_size 192 \
--dataloader_num_workers 16 \
--output_dir logs \
--use_ema \
--gradient_checkpointing \
--mixed_precision bf16

For monitoring training progress, we recommand wandb for its simplicity and powerful features.
