load_context() - încarcă artefactele la apelarea mlflow.pyfunc.load_model()predict() - primește date de intrare și efectuează evaluarea definită de utilizator# Class class MyPythonClass:# Function that prints Hello! def my_func(): print("Hello!")
# Create a new Object x = MyPythonClass()# Excute my_func function x.my_func()
"Hello!"
