Quick Start

For a quick tryout, you can use our latest Docker Image. Have a look at our Documentation for some basic examples.

Installation

You can install plenpy directly from PyPi via pip:

$ pip install plenpy

That's it!

Dependencies

Plenpy requires python >= 3.6 as it relies on Python syntax that has been introduced in Python 3.6 such as f-strings or type hinting.

The package dependencies are resolved automatically upon installation using pip. For development and testing dependencies, see the requirements.txt file. The package dependencies are stated in setup.py.

Manual Installation on Unix / Linux / macOS

If you want to install from source, the installation using make is straightforward and installs plenpy and its runtime dependencies automatically. If make is not available, or you are running Windows, see below.

Caution: A system wide installation using sudo is easy and possible but discouraged. Installing in a environment is recommended.

To install plenpy, first clone the project's git repository to a location of your desire and change directory to the project:

$ cd <path-to-plenpy>/
$ git clone [e-mail]:iiit-public/plenpy.git
$ cd plenpy

Then, install the library via:

$ make

Or, to have an editable install of plenpy, using

$ make editable

If no errors occur, we can check if the installation was successful by running the unit tests:

$ make test

That's it! The package should now be available.

Manual Installation on Windows

If make is not available on your system, the installation via pip is also straightforward. Instead of invoking make, install by calling (e.g. from the Anaconda prompt)

$ pip install -r requirements.txt .

Please note the . at the end, referring to the current folder <path-to-plenpy>/plenpy.

Testing

You can manually run the tests using pytest:

$ pytest <path-to-plenpy>/test/

Uninstallation

Uninstall plenpy using

$ pip uninstall plenpy

Documentation

The documentation can be found here.

You can also build the documentation yourself:

Dependencies and Building

The documentation is build using Sphinx. To install all necessary dependencies for the documentation, run

$ cd <path-to-plenpyr>
$ make
$ pip install -r docs/requirements.txt
$ cd docs
$ sphinx-apidoc -f -o ./ ../plenpy/
$ make html

This will create the full plenpy documentation in the docs/_build/html folder.
