DeepLab v3+ model in PyTorch. Support different backbones.

TODO

  • [x] Support different backbones
  • [x] Support VOC, SBD, Cityscapes and COCO datasets
  • [x] Multi-GPU training

Introduction

This is a PyTorch(0.4.1) implementation of DeepLab-V3-Plus. It
can use Modified Aligned Xception and ResNet as backbone. Currently, we train DeepLab V3 Plus
using Pascal VOC 2012, SBD and Cityscapes datasets.

Installation

The code was tested with Anaconda and Python 3.6. After installing the Anaconda environment:

  1. Clone the repo:

    git clone https://github.com/jfzhang95/pytorch-deeplab-xception.git
    cd pytorch-deeplab-xception
    
  2. Install dependencies:

    For PyTorch dependency, see pytorch.org for more details.

    For custom dependencies:

    pip install matplotlib pillow tensorboardX tqdm
    

Training

Fellow steps below to train your model:

  1. Configure your dataset path in mypath.py.

  2. Input arguments: (see full input arguments via python train.py --help):
