Update on Oct 18, 2019

Fixed some compatibility issue with PyTorch 1.2.0.

Prerequisites

The experiments can be reproduced with PyTorch 0.3.1 and CUDA 9.0 on Ubuntu 16.04. Here is one approach to set up:

1. Install Anaconda2 (optional).

mkdir tmp && cd tmp
wget https://repo.anaconda.com/archive/Anaconda2-5.1.0-Linux-x86_64.sh && bash Anaconda2-5.1.0-Linux-x86_64.sh

2. Install PyTorch.

# Select the correct version according to your environment. 
pip install http://download.pytorch.org/whl/cu90/torch-0.3.1-cp27-cp27mu-linux_x86_64.whl
pip install torchvision 

3. Install TensorboardX for visualization.

pip install tensorboardx

4. Download the pretrained VGG models and unzip under this directory via Google Drive or Baidu Pan.
