Overview of LMC

Environment

The code is developed and tested under the following environment:

• Python 3.9
• PyTorch 2.0.0
• CUDA 11.7

You can create the environment via:

conda create -n lmc python=3.9
conda activate lmc
conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia
pip install ftfy regex tqdm scikit-learn scipy pandas six timm
pip install transformers openai
pip install git+https://github.com/openai/CLIP.git

Preparation

Dataset

Tinyimagenet can be downloaded by running:

cd data
bash tinyimagenet.sh

Pre-trained model

To load CLIP pre-trained weights, you can visit official CLIP GitHub Repo and download CLIP "ViT-B/32" to pretrained_model using download address in this page.

To load DINO pre-trained weights, you can visit official DINOv2 and download "ViT-B/14 distilled" to pretrained_model using download address in this page.

Evaluation

To evaluate using our provided virtual open-set classes, please unzip tiny_img.zip and run:

python tinyimagenet_eval_msp.py --save_dir path\to\save\result --image_path path\to\unzipped\images

Note that here we provide virtual open-set classes and generated images that can yield slightly better results than the results provided in our paper for Tinyimagenet.
