        # What is Ludwig?
        
        Ludwig is a [declarative machine learning framework](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/what_is_ludwig/#why-declarative-machine-learning-systems)
        that makes it easy to define machine learning pipelines using a simple and
        flexible data-driven configuration system. Ludwig is suitable for a wide variety
        of AI tasks, and is hosted by the
        [Linux Foundation AI & Data](https://lfaidata.foundation/).
        
        The configuration declares the input and output features, with their respective
        data types. Users can also specify additional parameters to preprocess, encode,
        and decode features, load from pre-trained models, compose the internal model
        architecture, set training parameters, or run hyperparameter optimization.
        
        ![img](https://raw.githubusercontent.com/ludwig-ai/ludwig-docs/master/docs/images/ludwig_legos_unanimated.gif)
        
        Ludwig will build an end-to-end machine learning pipeline automatically, using
        whatever is explicitly specified in the configuration, while falling back to
        smart defaults for any parameters that are not.
        
        # Declarative Machine Learning
        
        Ludwig’s declarative approach to machine learning empowers you to have full
        control of the components of the machine learning pipeline that you care about,
        while leaving it up to Ludwig to make reasonable decisions for the rest.
        
        ![img](images/why_declarative.png)
        
        Analysts, scientists, engineers, and researchers use Ludwig to explore
        state-of-the-art model architectures, run hyperparameter search, scale up to
        larger than available memory datasets and multi-node clusters, and finally
        serve the best model in production.
        
        Finally, the use of abstract interfaces throughout the codebase makes it easy
        for users to extend Ludwig by adding new models, metrics, losses, and
        preprocessing functions that can be registered to make them immediately useable
        in the same unified configuration system.
        
        # Main Features
        
        - **[Data-Driven configuration system](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/how_ludwig_works)**
        
          A config YAML file that describes the schema of your data (input features,
          output features, and their types) is all you need to start training deep
          learning models. Ludwig uses declared features to compose a deep learning
          model accordingly.
        
          ```yaml
          input_features:
              - name: data_column_1
                type: number
              - name: data_column_2
                type: category
              - name: data_column_3
                type: text
              - name: data_column_4
                type: image
              ...
        
          output_features:
              - name: data_column_5
                type: number
              - name: data_column_6
                type: category
              ...
          ```
        
        - **[Training, prediction, and evaluation from the command line](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/command_line_interface)**
        
          Simple commands can be used to train models and predict new data.
        
          ```shell
          ludwig train --config config.yaml --dataset data.csv
          ludwig predict --model_path results/experiment_run/model --dataset test.csv
          ludwig eval --model_path results/experiment_run/model --dataset test.csv
          ```
        
        - **[Programmatic API](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/api/LudwigModel)**
        
          Ludwig also provides a simple programmatic API for all of the functionality
          described above and more.
        
          ```python
          from ludwig.api import LudwigModel
        
          # train a model
          config = {
              "input_features": [...],
              "output_features": [...],
          }
          model = LudwigModel(config)
          data = pd.read_csv("data.csv")
          train_stats, _, model_dir = model.train(data)
        
          # or load a model
          model = LudwigModel.load(model_dir)
        
          # obtain predictions
          predictions = model.predict(data)
          ```
        
        - **[Distributed training](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/distributed_training)**
        
          Train models in a distributed setting using [Horovod](https://github.com/horovod/horovod),
          which allows training on a single machine with multiple GPUs or multiple
          machines with multiple GPUs.
        
        - **[Serving](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/serving)**
        
          Serve models using FastAPI.
        
          ```shell
          ludwig serve --model_path ./results/experiment_run/model
          curl http://0.0.0.0:8000/predict -X POST -F "movie_title=Friends With Money" -F "content_rating=R" -F "genres=Art House & International, Comedy, Drama" -F "runtime=88.0" -F "top_critic=TRUE" -F "review_content=The cast is terrific, the movie isn't."
          ```
        
        - **[Hyperparameter optimization](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/hyperopt)**
        
          Run hyperparameter optimization locally or using [Ray Tune](https://docs.ray.io/en/latest/tune/index.html).
        
          ```shell
          ludwig hyperopt --config config.yaml --dataset data.csv
          ```
        
        - **[AutoML](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/automl)**
        
          Ludwig AutoML takes a dataset, the target column, and a time budget, and
          returns a trained Ludwig model.
        
        - **[Third-Party integrations](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/integrations)**
        
          Ludwig provides an extendable interface to integrate with third-party
          systems for tracking experiments. Third-party integrations exist for Comet
          ML, Weights & Biases, WhyLabs, and MLFlow.
        
        - **[Extensibility](https://ludwig-ai.github.io/ludwig-docs/latest/developer_guide)**
        
          Ludwig is built from the ground up with extensibility in mind. It is easy to
          add new data types by implementing clear, well-documented abstract classes
          that define functions to preprocess, encode, and decode data.
        
          Furthermore, new `torch nn.Module` models can be easily added by them to a
          registry. This encourages reuse and sharing new models with the community.
          Refer to the [Developer Guide](https://ludwig-ai.github.io/ludwig-docs/latest/developer_guide)
          for further details.
        
        # Quick Start
        
        For a full tutorial, check out the official [getting started guide](https://ludwig-ai.github.io/ludwig-docs/latest/getting_started/),
        or take a look at end-to-end [Examples](https://ludwig-ai.github.io/ludwig-docs/latest/examples).
        
        ## Step 1: Install
        
        Install from PyPi. Be aware that Ludwig requires Python 3.8+.
        
        ```shell
        pip install ludwig
        ```
        
        ## Step 2: Define a configuration
        
        Create a config that describes the schema of your data.
        
        Assume we have a text classification task, with data containing a sentence and class column like the following.
        
        |               sentence               |  class   |
        | :----------------------------------: | :------: |
        |  Former president Barack Obama ...   | politics |
        | Juventus hired Cristiano Ronaldo ... |  sport   |
        |  LeBron James joins the Lakers ...   |  sport   |
        |                 ...                  |   ...    |
        
        A configuration will look like this.
        
        ```yaml
        input_features:
        - name: sentence
          type: text
        
        output_features:
        - name: class
          type: category
        ```
        
        Starting from a simple config like the one above, any and all aspects of the model architecture, training loop,
        hyperparameter search, and backend infrastructure can be modified as additional fields in the declarative configuration
        to customize the pipeline to meet your requirements.
        
        ```yaml
        input_features:
        - name: sentence
          type: text
          encoder: transformer
          layers: 6
          embedding_size: 512
        
        output_features:
        - name: class
          type: category
          loss: cross_entropy
        
        trainer:
          epochs: 50
          batch_size: 64
          optimizer:
            type: adamw
            beat1: 0.9
          learning_rate: 0.001
        
        backend:
          type: ray
          cache_format: parquet
          processor:
            type: dask
          trainer:
            use_gpu: true
            num_workers: 4
            resources_per_worker:
              CPU: 4
              GPU: 1
        
        hyperopt:
          metric: f1
          sampler: random
          parameters:
            title.num_layers:
              lower: 1
              upper: 5
            trainer.learning_rate:
              values: [0.01, 0.003, 0.001]
        ```
        
        For details on what can be configured, check out [Ludwig Configuration](https://ludwig-ai.github.io/ludwig-docs/latest/configuration/)
        docs.
        
        ## Step 3: Train a model
        
        Simple commands can be used to train models and predict new data.
        
        ```shell
        ludwig train --config config.yaml --dataset data.csv
        ```
        
        ## Step 4: Predict and evaluate
        
        The training process will produce a model that can be used for evaluating on and obtaining predictions for new data.
        
        ```shell
        ludwig predict --model path/to/trained/model --dataset heldout.csv
        ludwig evaluate --model path/to/trained/model --dataset heldout.csv
        ```
        
        ## Step 5: Visualize
        
        Ludwig provides a suite of visualization tools allows you to analyze models' training and test performance and to
        compare them.
        
        ```shell
        ludwig visualize --visualization compare_performance --test_statistics path/to/test_statistics_model_1.json path/to/test_statistics_model_2.json
        ```
        
        For the full set of visualization see the [Visualization Guide](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/visualizations).

        # Advantages
        
        - **Minimal machine learning boilerplate**
        
          Ludwig takes care of the engineering complexity of machine learning out of
          the box, enabling research scientists to focus on building models at the
          highest level of abstraction. Data preprocessing, hyperparameter
          optimization, device management, and distributed training for
          `torch.nn.Module` models come completely free.
        
        - **Easily build your benchmarks**
        
          Creating a state-of-the-art baseline and comparing it with a new model is a
          simple config change.
        
        - **Easily apply new architectures to multiple problems and datasets**
        
          Apply new models across the extensive set of tasks and datasets that Ludwig
          supports. Ludwig includes a
          [full benchmarking toolkit](https://arxiv.org/abs/2111.04260) accessible to
          any user, for running experiments with multiple models across multiple
          datasets with just a simple configuration.
        
        - **Highly configurable data preprocessing, modeling, and metrics**
        
          Any and all aspects of the model architecture, training loop, hyperparameter
          search, and backend infrastructure can be modified as additional fields in
          the declarative configuration to customize the pipeline to meet your
          requirements. For details on what can be configured, check out
          [Ludwig Configuration](https://ludwig-ai.github.io/ludwig-docs/latest/configuration/)
          docs.
        
        - **Multi-modal, multi-task learning out-of-the-box**
        
          Mix and match tabular data, text, images, and even audio into complex model
          configurations without writing code.
        
        - **Rich model exporting and tracking**
        
          Automatically track all trials and metrics with tools like Tensorboard,
          Comet ML, Weights & Biases, MLFlow, and Aim Stack.
        
        - **Automatically scale training to multi-GPU, multi-node clusters**
        
          Go from training on your local machine to the cloud without code changes.
        
        - **Low-code interface for state-of-the-art models, including pre-trained Huggingface Transformers**
        
          Ludwig also natively integrates with pre-trained models, such as the ones
          available in [Huggingface Transformers](https://huggingface.co/docs/transformers/index).
          Users can choose from a vast collection of state-of-the-art pre-trained
          PyTorch models to use without needing to write any code at all. For example,
          training a BERT-based sentiment analysis model with Ludwig is as simple as:
        
          ```shell
          ludwig train --dataset sst5 --config_str “{input_features: [{name: sentence, type: text, encoder: bert}], output_features: [{name: label, type: category}]}”
          ```
        
        - **Low-code interface for AutoML**
        
          [Ludwig AutoML](https://ludwig-ai.github.io/ludwig-docs/latest/user_guide/automl/)
          allows users to obtain trained models by providing just a dataset, the
          target column, and a time budget.
        
          ```python
          auto_train_results = ludwig.automl.auto_train(dataset=my_dataset_df, target=target_column_name, time_limit_s=7200)
          ```
        
        - **Easy productionisation**
        
          Ludwig makes it easy to serve deep learning models, including on GPUs.
          Launch a REST API for your trained Ludwig model.
        
          ```shell
          ludwig serve --model_path=/path/to/model
          ```
        
          Ludwig supports exporting models to efficient Torschscript bundles.
        
          ```shell
          ludwig export_torchscript -–model_path=/path/to/model
          ```
