Installation

This project is based on MMDetection 3.x

It requires the following OpenMMLab packages:

  • MMEngine >= 0.6.0
  • MMCV-full >= v2.0.0rc4
  • MMDetection >= v3.0.0rc6
  • lvisapi
pip install openmim mmengine
mim install "mmcv>=2.0.0rc4"
pip install git+https://github.com/lvis-dataset/lvis-api.git
mim install mmdet>=3.0.0rc6

License

This project is released under the NTU S-Lab License 1.0.

Usage

Obtain CLIP Checkpoints

We use CLIP's ViT-B-32 model for the implementation of our method. Obtain the state_dict of the model from GoogleDrive and put it under checkpoints. Otherwise, pip install git+https://github.com/openai/CLIP.git and run

import clip
import torch
model, _ = clip.load("ViT-B/32")
torch.save(model.state_dict(), 'checkpoints/clip_vitb32.pth')

Training and Testing

The training and testing on OV-COCO are supported now.
