# Using Existing Model

*AI/ML Accelerator - MLflow is specifically built to track your ML experiments on the DNAnexus platform environment via the ML JupyterLab (another app in the AI/ML Accelerator package) environment. A license is required in order to use the AI/ML Accelerator package. For more information, please contact DNAnexus Sales via* [*sales@dnanexus.com*](mailto:sales@dnanexus.com)*.*

Once a model has been logged in the DNAnexus project by MLflow, you can load and use it for inference or further evaluation. Below are the instructions for retrieving the model path and loading it for use.

## **Retrieve the Model Path**

When you log a model, MLflow generates a run\_ID and stores the model in a specific path. To get the model path, simply click on the model in the **'Artifacts'** section of a **Run** and copy the Path as below.

## **Load the Model**

Once you have the model path, use the appropriate load\_model function to load the model from the specified path. Below are the two examples.

For generic models

```
loaded_model = mlflow.pyfunc.load_model("<model_path>")
predictions = loaded_model.predict(data)
```

For framework-specific models (e.g., scikit-learn)

```
loaded_model = mlflow.sklearn.load_model("<model_path>")
predictions = loaded_model.predict(data)
```
