Requirements

All required dependencies are listed in requirements.txt:

onnxruntime-gpu==1.19.2
torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu124
scikit-image
insightface
numpy==1.23

Install all dependencies with a single command: pip install -r requirements.txt

Datasets

Test datasets for inference validation can be downloaded from the following sources:

• IJB-C & IJB-B: Google Drive
• MFR-Ongoing: Challenge Page

LVFace Pretrained Models

Pretrained model weights for inference are available below in both ONNX and PyTorch (.pt) formats:

Step-by-Step Usage Guide

1. Installation & Environment Setup

First, clone the repository and navigate to the project directory:

# Clone the LVFace repository
git clone https://github.com/bytedance/LVFace.git

# Enter the project directory
cd LVFace

Then install all required dependencies using the provided requirements.txt:

# Install dependencies
pip install -r requirements.txt

2. Download Pretrained Models
Download the ONNX-format pretrained weights from the LVFace Pretrained Models section, then place them in a directory (e.g., ./LVFace_model/).

3. Run Inference
Execute the inference_onnx.py script to perform feature extraction and similarity calculation. A complete workflow example:

## Initialize the inferencer from inference_onnx.py
inferencer = LVFaceONNXInferencer(
   model_path="./models/vit_b_dp005_mask_005.onnx",  # Path to your ONNX model
   use_gpu=True  # Set to False for CPU-only inference
)

## Extract feature from local image
feat1 = inferencer.infer_from_image("path/to/image1.jpg")

## Extract feature from URL
feat2 = inferencer.infer_from_url("https://example.com/image1.jpg")

## Calculate cosine similarity
similarity = inferencer.calculate_similarity(feat1, feat2)
print(f"Similarity score: {similarity:.6f}")  # Output example: 0.892345

Note: The LVFaceONNXInferencer class is defined in inference_onnx.py, which handles ONNX model loading, image preprocessing, feature extraction, and similarity calculation in a unified interface. Ensure the model path and image paths are correctly specified before running.

Model Evaluation

Evaluation Steps

1. Modify the test dataset path (e.g., IJB-C, IJB-B) in the corresponding evaluation script (eval_ijbc.py).

2. Run the evaluation with pretrained model weights using the commands below:

Evaluation Commands

python eval_ijbc.py \
  --model-prefix path/to/LVFace-B_Glint360K.pt \
  --result-dir results \
  --network vit_b_dp005_mask_005 > LVFace-B_Glint360K.log 2>&1 &
