Created by Peng Xia, Xingtong Yu, ‪Ming Hu‬‬, Lie Ju, Zhiyong Wang, Peibo Duan, Zongyuan Ge.

💡Requirements

Environment

1. Python 3.8.*
2. CUDA 12.2
3. PyTorch
4. TorchVision

Install

Create a virtual environment and activate it.

conda create -n hgclip python=3.8
conda activate hgclip

The code has been tested with PyTorch 1.13 and CUDA 12.2.

pip install -r requirements.txt

⏳Dataset

Please first download the required datasets. Follow prepare_datasets.md to install the datasets.

📦Usage

Training & Evaluation

To train or evaluation our HGCLIP, you need to first generate and save the prototypes.

python generate_prototypes.py \
--dataset 'air' \
--batch_size 64 \
--gpu_id 0 

Then run

cd hgclip
python main.py \
--config configs/air/train_gnn.py

Zero-Shot Evaluation

To evaluation the performance of zero-shot CLIP, run

cd zsclip
python zero_shot.py \
--config configs/air/zero_shot_clip.py

Quick Start

The main script for training and evaluating model performance is hgclip/main.py. Here are the list of key arguments:

• --config: In this configuration file, you can define all the arguments included below.

• --device: cuda or cpu

• --gpu_id: gpu id

• --dataset: dataset name

• --batch_size

• --epochs

• --trainer: training method

  • CoOp

  • CoCoOp

  • MaPLe

  • VPT

  • PromptSRC

  • KgCoOp

  • HGCLIP

• --ctx_init: context initialization

• --n_ctx: context length for random initialization

• --lr: learning rate

• --optimizer: optimizer

  • sgd

  • adam

  • adamw
