-DP-GEN (Deep Generator) is a software written in Python, delicately designed to generate a deep learning based model of interatomic potential energy and force field. DP-GEN is dependent on [DeePMD-kit](https://github.com/deepmodeling/deepmd-kit/). With highly scalable interface with common softwares for molecular simulation, DP-GEN is capable to  automatically prepare scripts and maintain job queues on HPC machines (High Performance Cluster) and analyze results.
