DualPrompt PyTorch Implementation

This repository contains PyTorch implementation code for awesome continual learning method DualPrompt,
Wang, Zifeng, et al. "DualPrompt: Complementary Prompting for Rehearsal-free Continual Learning." ECCV. 2022.

The official Jax implementation is here.

Environment

The system I used and tested in

Ubuntu 20.04.4 LTS
Slurm 21.08.1
NVIDIA GeForce RTX 3090
Python 3.8

Usage

First, clone the repository locally:

git clone https://github.com/JH-LEE-KR/dualprompt-pytorch
cd dualprompt-pytorch

Then, install the packages below:

pytorch==1.12.1
torchvision==0.13.1
timm==0.6.7
pillow==9.2.0
matplotlib==3.5.3

These packages can be installed easily by

pip install -r requirements.txt

Data preparation

If you already have CIFAR-100 or ImageNet-R, pass your dataset path to --data-path.

The datasets aren't ready, change the download argument in datasets.py as follows

CIFAR-100

datasets.CIFAR100(download=True)

ImageNet-R

Imagenet_R(download=True)

Training

To train a model via command line:

Single node with single gpu

python -m torch.distributed.launch \
        --nproc_per_node=1 \
        --use_env main.py \
        <cifar100_dualprompt or imr_dualprompt> \
        --model vit_base_patch16_224 \
        --batch-size 24 \
        --data-path /local_datasets/ \
        --output_dir ./output

Single node with multi gpus

python -m torch.distributed.launch \
        --nproc_per_node=<Num GPUs> \
        --use_env main.py \
        <cifar100_dualprompt or imr_dualprompt> \
        --model vit_base_patch16_224 \
        --batch-size 24 \
        --data-path /local_datasets/ \
        --output_dir ./output

Also available in Slurm system by changing options on train_cifar100_dualprompt.sh or train_imr_dualprompt.sh properly.

Multinode train

Distributed training is available via Slurm and submitit:

pip install submitit

To train a model on 2 nodes with 4 gpus each:

python run_with_submitit.py <cifar100_dualprompt or imr_dualprompt> --shared_folder <Absolute Path of shared folder for all nodes>

Absolute Path of shared folder must be accessible from all nodes.
According to your environment, you can use NCLL_SOCKET_IFNAME=<Your own IP interface to use for communication> optionally.

Evaluation

To evaluate a trained model:

python -m torch.distributed.launch --nproc_per_node=1 --use_env main.py <cifar100_dualprompt or imr_dualprompt> --eval

Result

Test results on a single gpu.
