It also provides helpful tools to constrain or pin versions in recipes. Building a conda package requires installing conda-build and creating a conda recipe. You then use the conda build command to build the conda package from the conda recipe. You can build conda packages from a variety of source code projects, most notably Python. For help packing a Python project, see the Setuptools documentation. OPTIONAL: If you are planning to upload your packages to Anaconda Cloud, you will need an Anaconda Cloud account and client.

  • A Package for Developing Machine Learning-Based Chemically Accurate Energy and Density Functional Models
    DeePKS-kit: a package for developing machine learning-based chemically accurate energy and density functional models Yixiao Chena, Linfeng Zhanga, Han Wangb, Weinan Ea,c aProgram in Applied and Computational Mathematics, Princeton University, Princeton, NJ, USA bLaboratory of Computational Physics, Institute of Applied Physics and Computational Mathematics, Huayuan Road 6, Beijing 100088, People’s Republic of China cDepartment of Mathematics, Princeton University, Princeton, NJ, USA Abstract We introduce DeePKS-kit, an open-source software package for developing machine learning based energy and density functional models. DeePKS-kit is interfaced with PyTorch, an open-source machine learning library, and PySCF, an ab initio computational chemistry program that provides simple and customized tools for developing quantum chemistry codes. It supports the DeePHF and DeePKS methods. In addition to explaining the details in the methodology and the software, we also provide an example of developing a chemically accurate model for water clusters. Keywords: Electronic structure, Density functional theory, Exchange-correlation functional, Deep learning PROGRAM SUMMARY reached great accuracy in specific applications[4]. However, Program Title: DeePKS-kit in general, chemical accuracy cannot be easily achieved for Developer’s repository link: these methods, and the design of xc-functionals can take a https://github.com/deepmodeling/deepks-kit lot of efforts.

Tomasz Górecki (UAM) R programming 1 / 13 R Markdown – idea R Markdown provides an authoring framework for data science. You can use a single R Markdown file to both save and execute code, and generate high quality reports that can be shared with an audience. R Markdown was designed for easier reproducibility, since both the computing code and narratives are in the same document, and results are automatically generated from the source code. R Markdown supports dozens of static and dynamic/interactive output formats.
