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:

Clone the repo:

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

Install dependencies:

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

For custom dependencies:
```
pip install matplotlib pillow tensorboardX tqdm
```
