pip install flash_attn

📦Multi-Expr Dataset

We make public the first multi-portrait facial expression video dataset Multi-Expr Dataset, Please download it via the this link.

🧱Model Download

Models	Download Link	Notes
Wan2.1-I2V-14B-720P	🤗 Huggingface 🤖 ModelScope	Base model

🔑 Single-Portrait Inference

bash infer_single.sh

🔑 Multi-Portrait Inference

If you use input image and drive videos with multiple people, you can run as follows:

bash infer_multi.sh

If you use input image with multiple people and different multiple single-human driven videos, you can run as follows:

bash infer_multi_diff.sh

📦Speed and VRAM Usage

We present a detailed table here. The model is tested on a single A100.

torch_dtype	num_persistent_param_in_dit	Speed	Required VRAM
torch.bfloat16	None (unlimited)	15.5s/it	40G
torch.bfloat16	7*10**9 (7B)	32.8s/it	20G
torch.bfloat16	0	42.6s/it	5G
