DeepLab2: A TensorFlow Library for Deep Labeling

DeepLab2 is a TensorFlow library for deep labeling, aiming to provide a unified and state-of-the-art TensorFlow codebase for dense pixel labeling tasks, including, but not limited to semantic segmentation, instance segmentation, panoptic segmentation, depth estimation, or even video panoptic segmentation.

Deep labeling refers to solving computer vision problems by assigning a predicted value for each pixel in an image with a deep neural network. As long as the problem of interest could be formulated in this way, DeepLab2 should serve the purpose. Additionally, this codebase includes our recent and state-of-the-art research models on deep labeling. We hope you will find it useful for your projects.

Installation

See Installation.

Dataset preparation

The dataset needs to be converted to TFRecord. We provide some examples below.

• Cityscapes
  
• COCO
  
• KITTI-STEP
  
• MOTChallenge-STEP
  

Some guidances about how to convert your own dataset.

• Your Own Dataset

Running DeepLab2

See Getting Started. In short, run the following command:

To run DeepLab2 on GPUs, the following command should be used:

python trainer/train.py \
    --config_file=${CONFIG_FILE} \
    --mode={train | eval | train_and_eval | continuous_eval} \
    --model_dir=${BASE_MODEL_DIRECTORY} \
    --num_gpus=${NUM_GPUS}
