Installation of the package using package managers

The simplest way how to install and use the package is to install them using package managers: either pip

pip install ase2sprkkr

or conda

conda install -c ase2sprkkr ase2sprkkr

Further notes

In some systems, the pip utility for python3 is called pip3. If it is not installed, you can install it using the linux distribution package manager, e.g. in Debian/Ubuntu

apt install pip3

or

zypper install pip

in OpenSUSE

For the conda installation instructions, see the Anaconda documentation https://docs.anaconda.com/anaconda/install/linux/ however, for the users unexperienced with conda, the (simpler) pip way is recommended.

Install the packages from GIT (and/or source codes)

If you do not want to use public package managers as pip or conda, or you want to contribute to development, you can use GIT to obtain the package sources.

Requirements

• Python >= 3.7
• SPR-KKR (not checked by the installer)
• Python packages: ase, mendeleev, spglib, pyparsing
• Git (to obtain the sources)

Obtaining the package using GIT

git clone https://github.com/ase2sprkkr/ase2sprkkr.git
git checkout release

The first line fetches the code of the package. The second one checks out the recommended production version of the code.

If you want to obtain the current version of the (earlier-downloaded) code, run

git fetch
git checkout release

Alternatively, you can checkout master or develop branch

git checkout master

to obtain a newer (not thorougly tested yet) version or

git checkout develop

to obtain the bleeding edge version (feel free to try it, test it and report the bugs).

Using the package (without installing the pip/conda packages)

You can either just add the src directory to your PYTHONPATH, or you can build and install the package, as it is described below.

Installation of the package from the sources

To install the package, the simplest way is to use pip

python3 -m pip install .

Maybe, you will have to replace python3 with python. For an editable install, please run

python3 setup.py develop --user

and ignore some deprecation warning. Editable install is aimed for developers: in this type of install, only link to the current directory will be added to your local site-packages, which allows you to use the changesyou make to the source code.

Documentation of the package

The documentation is published online at https://ase2sprkkr.github.io/ase2sprkkr/

If you are using Git cloned sources, you can run

open docs/index.html

to see the (offline version of the) documentation. The documentation contains parts, that are generated from the docstrings in the source code. You can regenerate these by

make docs

Sphinx and sphinx-toolbox python packages (installable e.g. using pip) and pandoc (for generating README.md) are needed for the build.

However, the official build of Sphinx miss some attributes when it is used to build the documentation. So, till the pullrequest that corrects the Sphinx behavior will be merged into Sphinx, please use the following fork for building the documentation. https://github.com/lokik/sphinx.git
