Updates

• [27/03/2023] Training code out. Updated weights to the ImageNet trained. Modified MaskCLIP code to directly load weights from OpenCLIP model.
• [20/12/2023] Code release

Demo

Try our model!

Requirements

Set up the environment:

# Create conda environment
conda create -n clipdino python=3.9
conda activate clipdino
conda install pytorch==1.12.1 torchvision==0.13.1 cudatoolkit=[your CUDA version] -c pytorch
pip install -r requirements.txt

You will also need to install MMCV and MMSegmentation by running:

pip install -U openmim
mim install mmengine    
mim install "mmcv-full==1.6.0"
mim install "mmsegmentation==0.27.0

Running from the notebook

You can try our model through jupyter notebook demo.ipynb.

Running from command line

You can also try our demo from the command line:

python demo.py --file_path [path to the image file] --prompts [list of the text prompts separated by ',']

Example:

python demo.py --file_path assets/rusted_van.png --prompts "rusted van,foggy clouds,mountains,green trees" 

Reproducing results

Dataset preparation

In the paper, following previous works, we use 8 benchmarks; (i) w/ background: PASCAL VOC20, PASCAL Context59, and COCO-Object, and (ii) w/o background: PASCAL VOC, PASCAL Context, COCO-Stuff, Cityscapes, and ADE20k.

To run the evaluation, download and set up PASCAL VOC, PASCAL Context, COCO-Stuff164k, Cityscapes, and ADE20k datasets following MMSegmentation data preparation document.

COCO Object

COCO-Object dataset uses only object classes from COCO-Stuff164k dataset by collecting instance segmentation annotations. Run the following command to convert instance segmentation annotations to semantic segmentation annotations:

python tools/convert_coco.py data/coco_stuff164k/ -o data/coco_stuff164k/

Running evaluation

In order to reproduce our results simply run:

torchrun main_eval.py clip_dinoiser.yaml

or using multiple GPUs:

CUDA_VISIBLE_DEVICES=[0,1..] torchrun --nproc_per_node=auto main_eval.py clip_dinoiser.yaml

Training

Hardware Requirements: you'll need one gpu (~14GB) to run the training. Using NVIDIA GPU A5000 training takes approximately 3 hours.

Dataset preparation

Download ImageNet and update the ImageNet folder path in the configs/clip_dinoiser.yaml file.

Install FOUND

Install FOUND by running:

cd models;
git clone git@github.com:valeoai/FOUND.git
cd FOUND;
git clone https://github.com/facebookresearch/dino.git
cd dino; 
touch __init__.py
echo -e "import sys\nfrom os.path import dirname, join\nsys.path.insert(0, join(dirname(__file__), '.'))" >> __init__.py; cd ../;

Run training

To run the training simply run:

CUDA_VISIBLE_DEVICES=0 torchrun --nproc_per_node=auto train.py clip_dinoiser.yaml

Currently, we only support single gpu training.
