Puro include a signature with your model, pass signature object as an argument preciso the appropriate log_model call, addirittura

g. sklearn.log_model() . The model signature object can be created by hand or inferred from datasets with valid model inputs (addirittura.g. the addestramento dataset with target column omitted) and valid model outputs (e.g. model predictions generated on the addestramento dataset).

Column-based Signature Example

The following example demonstrates how onesto filtre a model signature for a simple classifier trained on the Iris dataset :

Tensor-based Signature Example

The following example demonstrates how preciso filtre verso model signature for a simple classifier trained on the MNIST dataset :

Model Spinta Example

Similar preciso model signatures, model inputs can be column-based (i.anche DataFrames) or tensor-based (i.e numpy.ndarrays). Per model incentivo example provides an instance of verso valid model stimolo. Stimolo examples are stored with the model as separate artifacts and are referenced mediante the the MLmodel file .

How Preciso Log Model With Column-based Example

For models accepting column-based inputs, an example can be verso solo supremazia or verso batch of records. The sample input can be passed durante as verso Pandas DataFrame, list or dictionary. The given example will be converted preciso a Pandas DataFrame and then serialized preciso json using the Pandas split-oriented format. Bytes are base64-encoded. The following example demonstrates how you can log a column-based molla example with your model:

How Esatto Log Model With Tensor-based Example

For models accepting tensor-based inputs, an example must be per batch of inputs. By default, the axis 0 is the batch axis unless specified otherwise in the model signature. The sample stimolo can be passed in as verso numpy ndarray or a dictionary mapping a string puro a numpy array. The following example demonstrates how you can log verso tensor-based stimolo example with your model:

Model API

You can save and load MLflow Models in multiple ways. First, MLflow includes integrations with several common libraries. For example, mlflow.sklearn contains save_model , log_model , and load_model functions for scikit-learn models. Second, you can use the mlflow.models.Model class puro create and write models. This class has four key functions:

add_flavor to add per flavor to the model. Each flavor has per string name and a dictionary of key-value attributes, where the values can be any object that can be serialized sicuro YAML.

Built-Con Model recensioni muddy matches Flavors

MLflow provides several norma flavors that might be useful durante your applications. Specifically, many of its deployment tools support these flavors, so you can commercio internazionale your own model in one of these flavors puro benefit from all these tools:

Python Function ( python_function )

The python_function model flavor serves as a default model interface for MLflow Python models. Any MLflow Python model is expected esatto be loadable as per python_function model. This enables other MLflow tools to rete informatica with any python model regardless of which persistence ondoie or framework was used puro produce the model. This interoperability is very powerful because it allows any Python model preciso be productionized mediante a variety of environments.

Con accessit, the python_function model flavor defines verso generic filesystem model format for Python models and provides utilities for saving and loading models esatto and from this format. The format is self-contained in the sense that it includes all the information necessary preciso load and use verso model. Dependencies are stored either directly with the model or referenced cammino conda environment. This model format allows other tools puro integrate their models with MLflow.

How Preciso Save Model As Python Function

Most python_function models are saved as part of other model flavors – for example, all mlflow built-mediante flavors include the python_function flavor per the exported models. Durante addenda, the mlflow.pyfunc diversifie defines functions for creating python_function models explicitly. This ondoie also includes utilities for creating custom Python models, which is a convenient way of adding custom python code esatto ML models. For more information, see the custom Python models documentation .
