Requirements

The script has been tested running under Python 3.6.9, with the following packages installed (along with their dependencies):

• pytorch (tested on 1.7.1)
• torch_geometric (tested on 1.6.3)
• scipy (tested on 1.5.4)
• numpy (tested on 1.19.5)
• networkx (tested on 2.5.1)
• sklearn (tested on 0.24.2)
• deeprobust (tested on 0.1.1)

Datasets

The datasets are from PyG, which can be referred to the docs.

Run

• For the defense experiment on Cora dataset, one-edge targeted attack under Nettack (default setting):

python LFR_test.py
