Introduction

This repo is the official implementation of Why Is Prompt Tuning for Vision-Language Models Robust to Noisy Labels?.

Install

Setup conda environment (recommended).:

############ Conda Environment Installation ############

# Fetch the miniconda script
export HOME=$PWD
wget -q https://repo.anaconda.com/miniconda/Miniconda3-py37_4.12.0-Linux-x86_64.sh -O miniconda.sh
sh miniconda.sh -b -p $HOME/miniconda3
rm miniconda.sh
export PATH=$HOME/miniconda3/bin:$PATH

# Initialize conda
source $HOME/miniconda3/etc/profile.d/conda.sh
hash -r
conda config --set always_yes yes --set changeps1 yes
conda activate dassl

############ Dassl Installation ############

# Clone the Dassl repository
git clone https://github.com/KaiyangZhou/Dassl.pytorch.git
cd Dassl.pytorch/
git reset --hard ac6e44194b2f90e325f477aadd6d9bc3a92ce255

# Establish a new conda environment
conda create -n dassl python=3.7

# Activate the new environment
conda activate dassl

# Install the required dependencies
pip install -r requirements.txt

# Install PyTorch (version 1.11.0 or above) and torchvision
conda install pytorch==1.11.0 torchvision==0.12.0 cudatoolkit=11.3 -c pytorch

# Set up the Dassl library (No need to rebuild even if the source code changes)
python setup.py develop

############ PTNL Installation ############

# Navigate back to the parent directory
cd ..

# Clone the PTNL repository
git clone https://github.com/CEWu/PTNL
cd PTNL/

# Install necessary packages for CLIP
pip install -r requirements.txt

######## Note ########
# Two symbolic links, `data` and `temp_analyze_results_miltiple`, exist in the repository. It is recommended that these be pointed to locations with sufficient storage capacity.

rm data temp_analyze_results_miltiple # remove the existing links
ln -s ${your_data_path} ./data
ln -s ${your_temp_analyze_results_miltiple_path} ./temp_analyze_results_miltiple

# Installation complete

Datasets

Please follow the instructions at CoOp Datasets Instructions to prepare all datasets.

Training

Obtain Psuodo-labels and Save Model's logits

CUDA_VISIBLE_DEVICES=0 bash get_info.sh sscaltech101 anay_rn50 end 16 -1 False

Prompt Tuning with Noisy Labels

Training with samples with noisy (2 out of 16 shots training samples are noisy labels.)

CUDA_VISIBLE_DEVICES=0 bash upl_train.sh sscaltech101 rn50_ep50 end 16 16 False True rn50_random_init 2

9 arguments listed sequentially as follows:

• dataset config (others in configs/datasets)
• model config (only rn50_ep50)
• class token position (end or middle)
• number of context tokens
• number of shots (1, 2, 4, 8, 16)
• class-specific context (False or True)
• CLASS_EQULE True of False
• log tag (only rn50_random_init)
• number of false positive training samples per class

PS. under scripts, there are eight scripts (upl_train_*.sh) shring 16 seeds to speed up training process on 8 GPUs.

Ensemble Testing

Test with existing files after prompt tuning with noisy labels (2 out of 16 shots training samples are noisy labels.)

bash upl_test_existing_logits.sh sscaltech101 rn50_ep50 end 16 16 False True 2

8 arguments listed sequentially as follows:

• dataset config (others in configs/datasets)
• model config (only rn50_ep50)
• class token position (end or middle)
• number of context tokens
• number of shots (1, 2, 4, 8, 16)
• class-specific context (False or True)
• CLASS_EQULE True of False
• number of false positive training samples per class
