Code for the paper: Semi-Supervised Graph Prototypical Networks for Hyperspectral Image Classification.

Please simply run 'SSGPN_IP.py' to reproduce the SSGPN results on IndianPines data set. The groundtruth and the obtained classification map are shown below. We have successfully test it on Ubuntu 16.04 with Tensorflow 1.13.1 and GTX 1080 Ti GPU.
