CrySPY (pronounced as crispy) is a crystal structure prediction tool written in Python.
CrySPY automates the following:

• Structure generation
• Submitting jobs for structure optimization
• Collecting data for structure optimization
• Selecting candidates using machine learning

CrySPY can be install by pip install csp-cryspy.
