How to use CH and image_struct repositories

Please read Software Requirement of README file (https://github.com/exalearn/online_rl_ch#software-requirement) to understand how to use ch and image_struct

Software Requirement

• Python 3.7 with PyTorch
• You can get submodules of "CH simulation" and "image structure" by cloning this repository recursively
• Use docker branch for image_structure, and docker-devel branch for cahnhilliard_2d

2D simulation by Anthony M. DeGennaro

Image Structure by Anthony M. DeGennaro and Kevin G. Yager

• Anthony modified Kevin's image structure generator, and it outputs about 200 components for each image by default.
