mkurman Overview
ZenML is an MLOps framework for portable, reproducible ML pipelines. It provides a standardized pipeline abstraction with built-in tracking, caching, artifact management, and integration with major ML and cloud tools.
Installation
uv pip install zenml
Basic Pipeline
from zenml import pipeline, step
@step
def load_data() -> dict:
return {"data": [1, 2, 3], "labels": [0, 1, 0]}
@step
def train_model(data: dict) -> str:
return f"Trained on {len(data['data'])} samples"
@pipeline
def training_pipeline():
data = load_data()
model = train_model(data)
training_pipeline()
Caching
# Steps are automatically cached — rerunning only changes
@step(enable_cache=True)
def preprocess(raw: dict) -> dict:
return {"features": [x * 2 for x in raw["data"]]}
# Changing parameters invalidates cache
@step
def train_with_params(data: dict, lr: float = 0.01) -> str:
return f"Trained with lr={lr}"
