pytorch-deeplab-xception

Update on 2018/12/06. Provide model trained on VOC and SBD datasets.

Update on 2018/11/24. Release newest version code, which fix some previous issues and also add support for new backbones and multi-gpu training. For previous code, please see in previous branch

TODO

  • Support different backbones
  • Support VOC, SBD, Cityscapes and COCO datasets
  • 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.

Results

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

Follow 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):
