# Transforms
Save and load models with transform script, register them or publish them as an API through DS Lab module.

*Check out a walk-through on how to use the Transform script inside Notebook.*
{% endhint %}
You can write or upload a script containing the transform function to a Notebook and save a model based on it. You can also register the model as an API service. This entire process is completed in the below-given steps:
## Saving and loading a Model with Transform script
* Navigate to a Notebook.
* Add a Code cell. Write or provide a transform script to the cell (In this case, it has been supplied in three cells).
* Run the cell(s) (In this case, run all the three cells).
* Add a new code cell and define the model.
* Add another cell and click the ***Save Model*** option for the newly added code cell.
* Specify the model name and type in the auto-generated script in the next code cell.
* Run the cell.
* Open the ***Transforms*** tab.
* The model gets saved under the ***Transforms*** tab.
* Add a new code cell.
* Load the transform model by using the checkbox.
* Run that cell.
* Insert a new code cell.
* Click the Transforms option for the code cell.
* The auto-generated script appears.
* Specify the train data.
* Run the code cell.
* It will display the transformed data below.
## Registering a Transform Model
* Open the ***Transforms*** tab inside a Notebook.
* Click the ellipsis icon for the saved transform.
* Select the ***Register*** option for a listed transform.
* The Register Model dialog box opens to confirm the action.
* Click the ***Yes*** option.
* A confirmation message appears to inform the completion of the action.
* The model gets registered and listed under the ***Registered*** list of the models.
* Open a pipeline workflow with a DS Lab model runner component.
* The registered model gets listed under the ***Meta Information*** tab of the DS Lab model runner component inside the Data Pipeline module.
## Publishing a Transform Model as API
The steps to publish a model as an API that contains transform remain the same as described for a Data Science Model. Refer to the [***Register a Model as an API Service*** page.](/data-science-lab-5/tabs-for-a-dsl-project/model/register-a-model-as-an-api-service.md)
