magic_animate_unofficial

This unofficial training code is primarily adapted from Magic Animate and Animatediff.

ToDo

• Release Training Code.
• Release pre-trained weights.

Features

• Utilizes Deepspeed training with a resolution of 768*512, and a batch size = 2 per GPU using V100-32G.
• We've altered the condition from dense-pose to dwpose, which differs from Magic Animate. Feel free to revert this change if necessary.
• We employ a fine-grained image prompt from IP-Adapter instead of the EMPTY text prompt used in Magic Animate. You can revert this change if required.

from animatediff.magic_animate.resampler import Resampler
# define a resampler
image_proj_model = Resampler(
                dim=cross_attention_dim,
                depth=4,
                dim_head=64,
                heads=12,
                num_queries=64,
                embedding_dim=1280,
                output_dim=cross_attention_dim,
                ff_mult=4,
            )
# extract fine-grained features of reference image for cross-attention guidance
# project from (batch_size, 257, 1280) to (batch_size, 64, 768); replace empty text embeddings with this.
encoder_hidden_states = image_proj_model(image_prompts)

Requirements

see 'requirements.txt'

To support DWPose which is dependent on MMDetection, MMCV and MMPose

pip install -U openmim
mim install mmengine
mim install "mmcv>=2.0.1"
mim install "mmdet>=3.1.0"
mim install "mmpose>=1.1.0"

Data

To prepare your videos, create a JSON file with a list of video directories. Then, update the "json_path" value in "./configs/training/aa_train_stage1.yaml" to point to your JSON file. You can use the public fashion dataset for fast prototyping.

Inference

We offer a model weight Google drive link that has been trained using 2,000 dance videos sourced from the web, and subsequently fine-tuned with fashion videos.

python3 infer.py

Please note that this weight was not trained from scratch; instead, it was initialized with the official weight from Magic Animate. Additionally, this weight does not utilize the IPAdapter as we originally intended. The presence of background artifacts could potentially be attributed to the fact that very few training videos have a white background as in fashion videos. Admittedly, this model is far from perfect. We hope this could be some little help for fast prototyping.

Training

# the default settings support 1 node, 8 gpus training
export HOST_NUM=1           # total nodes 
export INDEX=0              # node rank [0, 1, .., HOST_NUM]
export CHIEF_IP=localhost   # mater_ip for multi-node training
export HOST_GPU_NUM=8       # total number of gpus each node

PROCESS_NUM=$((HOST_GPU_NUM * HOST_NUM))
echo ${PROCESS_NUM}

Evalutaion

The evaluation code is identical to that of Magic Animate.

The majority of the network designs are provided by magic-animate. AnimateDiff supplies the training code. Additionally, there is a concurrent nice work unofficial animate anyone.
