SimREC

Python PyTorch MAC-Group

SimREC is a simple and lightweight codebase for the research of referring expression comprehension and segmentation, supporting large-scale pre-training and multi-task learning. SimREC includes the official implementations of our paper "Multi-task Collaborative Network for Joint Referring Expression Comprehension and Segmentation" and "What Goes beyond Multi-modal Fusion in One-stage Referring Expression Comprehension: An Empirical Study" . More models will be updated.

Updates

  • (2022/4/20) A novel point-based prediction paradigm SeqTR is released in here, which will be updated in this repository.
  • (2022/4/20) Implement MCN for SimREC project.
  • (2022/4/19) Release our SimREC project.

Installation

  • Clone this repo
git clone https://github.com/luogen1996/SimREC.git
cd SimREC
  • Create a conda virtual environment and activate it
conda create -n simrec python=3.7 -y
conda activate simrec
pip install -r requirements.txt
wget https://github.com/explosion/spacy-models/releases/download/en_vectors_web_lg-2.1.0/en_vectors_web_lg-2.1.0.tar.gz -O en_vectors_web_lg-2.1.0.tar.gz
pip install en_vectors_web_lg-2.1.0.tar.gz

Data preparation

  •  Follow the instructions of DATA_PRE_README.md to generate training data and testing data.
  •  Download the pretrained weights of backbone (vgg, darknet, cspdarknet, DResNet, etc.). Expect for DResNet, all pretrained backbones are trained on COCO 2014 train+val set while removing the images appeared in the val+test sets of RefCOCO, RefCOCO+ and RefCOCOg (nearly 6500 images). Please follow the instructions of DATA_PRE_README.md to download them.

Training and Evaluation

  1. Config preparation. Prepare your own configs in configs, you don't need to rewrite all the contents in config every time.You can import the config as a python file to use the default configs in configs/common as follows:
# your own config.py
from simrec.config import LazyCall
from .common.dataset import dataset
from .common.train import train
from .common.optim import optim
from .common.models.simrec import model

# modify the config depend your own need
dataset.ann_path["refcoco"] = "path/to/refcoco_data"
train.output_dir = "./path/to/output_dir"
...
  1. Train the model. Run bash/train.sh under the tools to start training, for example, training simrec model on 4 GPUs:
bash tools/train.sh config/simrec_refcoco_scratch.py 4

The training logs, tensorboard logs, config.yaml and model checkpoints will be automatically saved under cfg.train.output_dir.

  1. Resume training. We support two resume training mode. You can resume from a specific checkpoint or resume from the latest checkpoint:
  • Auto resume from last_checkpoint.pth:
# config.py
from .common.train import train
train.auto_resume.enabled = True

Setting train.auto_resume.enabled=True, which will automatically resume from last_checkpoint.pth saved in cfg.train.output_dir.

  • Resume from a specific checkpoint
# config.py
from .common.train import train

# disable auto resume first
train.auto_resume.enabled = False

# modify the resume path
train.resume_path = "path/to/specific/checkpoint.pth"

Setting train.resume_path to the specific checkpoint.pth you want to resume from.

  1. Test the model. Run bash/eval.sh under tools to evaluate the saved weight.
bash tools/eval.sh config/simrec_refcoco_scratch.py 4 /path/to/checkpoint

Model Zoo

SimREC supports all benchmarks of REC and RES, and can easily achieve very competitive performance. More results are available in Model Zoo.
