        ## Installation ![PyPI - Python Version](https://img.shields.io/pypi/pyversions/pykeen) ![PyPI](https://img.shields.io/pypi/v/pykeen)
        
        The latest stable version of PyKEEN can be downloaded and installed from
        [PyPI](https://pypi.org/project/pykeen) with:
        
        ```bash
        $ pip install pykeen
        ```
        
        The latest version of PyKEEN can be installed directly from the
        source on [GitHub](https://github.com/pykeen/pykeen) with:
        
        ```bash
        pip install git+https://github.com/pykeen/pykeen.git
        ```
        
        More information about installation (e.g., development mode, Windows installation, extras)
        can be found in the [installation documentation](https://pykeen.readthedocs.io/en/latest/installation.html).
        
        ## Quickstart [![Documentation Status](https://readthedocs.org/projects/pykeen/badge/?version=latest)](https://pykeen.readthedocs.io/en/latest/?badge=latest)
        
        This example shows how to train a model on a dataset and test on another dataset.
        
        The fastest way to get up and running is to use the pipeline function. It
        provides a high-level entry into the extensible functionality of this package.
        The following example shows how to train and evaluate the [TransE](https://pykeen.readthedocs.io/en/latest/api/pykeen.models.TransE.html#pykeen.models.TransE)
        model on the [Nations](https://pykeen.readthedocs.io/en/latest/api/pykeen.datasets.Nations.html#pykeen.datasets.Nations)
        dataset. By default, the training loop uses the [stochastic local closed world assumption (sLCWA)](https://pykeen.readthedocs.io/en/latest/reference/training.html#pykeen.training.SLCWATrainingLoop)
        training approach and evaluates with [rank-based evaluation](https://pykeen.readthedocs.io/en/latest/reference/evaluation/rank_based.html#pykeen.evaluation.RankBasedEvaluator).
        
        ```python
        from pykeen.pipeline import pipeline
        
        result = pipeline(
            model='TransE',
            dataset='nations',
        )
        ```
        
        The results are returned in an instance of the [PipelineResult](https://pykeen.readthedocs.io/en/latest/reference/pipeline.html#pykeen.pipeline.PipelineResult)
        dataclass that has attributes for the trained model, the training loop, the evaluation, and more. See the tutorials on
        [understanding the evaluation](https://pykeen.readthedocs.io/en/latest/tutorial/understanding_evaluation.html)
        and [making novel link predictions](https://pykeen.readthedocs.io/en/latest/tutorial/making_predictions.html).
        
        PyKEEN is extensible such that:
        
        - Each model has the same API, so anything from ``pykeen.models`` can be dropped in
        - Each training loop has the same API, so ``pykeen.training.LCWATrainingLoop`` can be dropped in
        - Triples factories can be generated by the user with ``from pykeen.triples.TriplesFactory``
        
        The full documentation can be found at https://pykeen.readthedocs.io.
        
        ## Implementation
        
        Below are the models, datasets, training modes, evaluators, and metrics implemented
        in ``pykeen``.
        
        ### Datasets (25)
        
        The citation for each dataset corresponds to either the paper describing the dataset,
        the first paper published using the dataset with knowledge graph embedding models,
        or the URL for the dataset if neither of the first two are available.

        ## Experimentation
        
        ### Reproduction
        
        PyKEEN includes a set of curated experimental settings for reproducing past landmark
        experiments. They can be accessed and run like:
        
        ```bash
        pykeen experiments reproduce tucker balazevic2019 fb15k
        ```
        
        Where the three arguments are the model name, the reference, and the dataset.
        The output directory can be optionally set with `-d`.
        
        ### Ablation
        
        PyKEEN includes the ability to specify ablation studies using the
        hyper-parameter optimization module. They can be run like:
        
        ```bash
        pykeen experiments ablation ~/path/to/config.json
        ```
        
        ### Large-scale Reproducibility and Benchmarking Study
        
        We used PyKEEN to perform a large-scale reproducibility and benchmarking study which are described in
        [our article](https://arxiv.org/abs/2006.13365):
        
        ```bibtex
        @article{ali2020benchmarking,
          title={Bringing Light Into the Dark: A Large-scale Evaluation of Knowledge Graph Embedding Models Under a Unified Framework},

          year={2020}
        }
        ```
        
        We have made all code, experimental configurations, results, and analyses that lead to our interpretations available
        at https://github.com/pykeen/benchmarking.
