## Building an Integrated MLOps Pipeline

The tools curated in Awesome Python are designed to interoperate. Below are three practical implementations combining multiple libraries from the list.

### Airflow Orchestration with DVC and MLflow

This DAG combines **Apache Airflow** for scheduling, **DVC** for data versioning, and **MLflow** for experiment tracking:

```python
from airflow import DAG
from airflow.operators.bash import BashOperator
from datetime import datetime

default_args = {"owner": "ml-team", "start_date": datetime(2024, 1, 1)}
with DAG("ml_pipeline", schedule_interval="@daily", default_args=default_args) as dag:
    # Pull latest data and DVC pipeline definitions

    dvc_pull = BashOperator(
        task_id="dvc_pull",
        bash_command="dvc pull && dvc repro preprocess.dvc"
    )

    # Run model training and log to MLflow

    train = BashOperator(
        task_id="train",
        bash_command="""
        export MLFLOW_TRACKING_URI=http://mlflow.example.com
        python train.py --data data/processed --mlflow
        """
    )

    dvc_pull >> train

```

### Prefect Flow with Feast and BentoML

This workflow uses **Prefect** to orchestrate a **Feast** feature store refresh followed by **BentoML** model deployment:

```python
from prefect import flow, task
import subprocess
import bentoml

@task
def refresh_feature_store():
    # Assuming Feast repo is version-controlled with Git

    subprocess.run(["git", "pull"], check=True)
    subprocess.run(["feast", "materialize-incremental"], check=True)

@task
def deploy_model():
    # Load the latest model from MLflow registry

    model = mlflow.pyfunc.load_model(model_uri="models:/my_model/Production")
    # Save with BentoML and start a REST API

    bento = bentoml.save_model("my_model", model)
    bentoml.serve(bento)

@flow
def mlops_flow():
    refresh_feature_store()
    deploy_model()

if __name__ == "__main__":
    mlops_flow()

```

### Distributed Training with Ray and ClearML

This example demonstrates **Ray** distributed compute integrated with **ClearML** experiment tracking:

```python
import ray
from ray import train
from ray.train import Trainer
from clearml import Task

# Initialise ClearML task for logging

task = Task.init(project_name="ray-demo", task_name="distributed_train")

def train_step(config):
    # Example: simple PyTorch training loop

    import torch, torch.nn as nn, torch.optim as optim
    model = nn.Linear(10, 1)
    optimizer = optim.SGD(model.parameters(), lr=0.01)
    loss_fn = nn.MSELoss()
    for epoch in range(5):
        # dummy data

        x = torch.randn(32, 10)
        y = torch.randn(32, 1)
        pred = model(x)
        loss = loss_fn(pred, y)
        optimizer.zero_grad()
        loss.backward()
        optimizer.step()
        # Log to ClearML

        task.get_logger().report_scalar(
            "loss", "train", iteration=epoch, value=loss.item()
        )

ray.init()
trainer = Trainer(backend="ray")
trainer.start()
trainer.run(train_step)
trainer.shutdown()

```
