Python Transformation Use Case

You work for a pharmaceutical company and you are studying data on flower formation in foxglove in your research to provide a better treatment for heart diseases. You want to find out whether the common foxglove Digitalis purpurea or the woolly foxglove Digitalis lanata can provide a better prognosis for the development of a disease.
To perform your research, you must classify data on the length and width of the flower sepals and petals by flower species. To classify the data, you developed a pre-trained model outside of the Developer tool.
You operationalize the pre-trained model in the Developer tool. In the Developer tool, you create a mapping that contains a Python transformation. In the Python transformation, you list the pre-trained model as a resource file. You write a Python script that accesses the pre-trained model. You pass the data on flower sepals and petals to the Python transformation to classify the data by foxglove species.
The following image shows the mapping that you might create:
This image shows a mapping in the Developer tool. The mapping contains a Read transformation, a Python transformation, and a Write transformation. The Read transformation contains the following ports: sepal_length, sepal_width, petal_length, petal_width, and true_class. The ports are linked to the downstream Python transformation. The ports are input ports in the Python transformation. Output ports are configured in the Python transformation based on the input ports. The output ports in the Python transformation are linked to the downstream Write transformation.
The following image shows the Python code you might write to access the pre-trained model in the Python transformation:
This image shows the Python tab of the Python transformation. The Python tab displays the resource file for the pre-trained model and the Python code that the Python transformation runs.
The Python transformation processes the data in the input ports according to the Python script and writes the classed data to the output ports.
