fcn.pytorch

PyTorch implementation of Fully Convolutional Networks, main code modified from pytorch-fcn.

Requirements

• pytorch
• torchvision
• ignite
• yacs
• tensorboardX
• tensorflow (for tensorboard)

Get Started

The designed architecture follows this guide PyTorch-Project-Template, you can check each folder's purpose by yourself.

Prepare Dataset

You can open the terminal and run the bash command to get VOC2012 dataset

bash get_data.sh

or you can just copy this url download by yourself

Training

Most of the configuration files that we provide are in folder configs. You just need to modify dataset root, vgg model weight and output directory. There are a few possibilities:

1. Modify configuration file and run

You can modify train_fcn32s.yml first and run following code

python3 tools/train_fcn.py --config_file='configs/train_fcn32s.yml'

2. Modify the cfg parameters

You can change configuration parameter such as learning rate or max epochs in command line.

python3 tools/train_fcn.py --config_file='configs/train_fcn32s.yml' SOLVER.BASE_LR 0.0025 SOLVER.MAX_EPOCHS 8

Results

We are training these models on VOC2012 train.txt and testing on val.txt, and we also use torchvision pretrained vgg16 rather than caffe pretrained. So the results maybe are different from the origin paper.
