Run Python Scripts

Thanks to the Python engine, you can execute Python code interacting with the partition from inside a Model Class logic.

To achieve this goal, follow these steps:

Decide which image flavour of the Python engine to run.
For your partition, request a new Calculation Engine of the type Python via PlatformManager. (The engine is then executed through a Job Trigger Calculation.)
Write your logic, script and test it.

Script Sample

Here is a small example of running a script in the Python engine from a Groovy logic

// These parameters will be available to the python job using `pyfx.get_context().parameters()`
def params = [
        foo: 1234,
        bar: 'baz',
]

// The python script you want to run
def script = '''
import pyfx
foo = pyfx.get_context().parameters()["foo"]
print(f'Hello {foo}')
''')

model.startJobTriggerCalculation(
        'cregistry.pricefx.eu/engineering/pricefx-python-engine/datascience',
        'latest', // NOTE for production you *should* change this to a specific version to avoid unexpected breakage
        api.jsonEncode([script: script, parameters: params]),
        'py'
)

Example Logic

You can find a complete sample logic using the Python engine at https://gitlab.pricefx.eu/logic/python-engine-samples-logic.

This logic can be used as a starting point for your own projects.
