Saving & loading a Data Science Lab model

Check-out the walk-through on how to save and load a DSL Model.

Save and load a model

Once the Notebook script is executed successfully, the users can save them as a model. The saved model can be loaded into the Notebook.

Saving a Data Science Lab Model

• Navigate to a Notebook.

• Write code using the following sequence:

  • Read DataFrame

  • Define test and train data

  • Create a model

• Execute the script by running the code cell.

Sample Script for a Data Science Model

• Get a new cell.

• Click the Save Model option.

• A code gets generated in the newly added code cell.

• Give a model name to specify the model and model type as ml.

• Execute the code cell.

• After the code gets executed, the Model gets saved under the Models tab.

Please Note: The newly saved model gets saved under the unregistered category given inside the Models tab.

Function Parameters

• model - Trained model variable name.

• modelName - Desired name given by user for the trained model.

• modelType - Type in which model can be saved.

• X - This array contains the input features or predictors used to train the model. Each row in the X_train array represents a sample or observation in the training set, and each column represents a feature or variable.

• Y - This array contains the corresponding output or response variable for each sample in the training set. It is also called the target variable, dependent variable, or label. The Y_train array has the same number of rows as the X_train array.

• estimator_type - The estimator_type of a data science model refers to the type of estimator use.

Specify a Data Science Lab Model by giving a name

Loading a Data Science Lab Model

• Open the Models tab.

• Access the Unregistered category.

• The saved model will be available under the Models tab. Select the model by using the given checkbox to load it.

• The model gets loaded into a new cell.

• Run the cell.
