Install BentoML:
# Requires Python≥3.9
pip install -U bentoml
Define APIs in a service.py file.
import bentoml
@bentoml.service(
image=bentoml.images.PythonImage(python_version="3.11").python_packages("torch", "transformers"),
)
class Summarization:
def __init__(self) -> None:
import torch
from transformers import pipeline
device = "cuda" if torch.cuda.is_available() else "cpu"
self.pipeline = pipeline('summarization', device=device)
@bentoml.api(batchable=True)
def summarize(self, texts: list[str]) -> list[str]:
results = self.pipeline(texts)
return [item['summary_text'] for item in results]Install PyTorch and Transformers packages to your Python virtual environment.
pip install torch transformers # additional dependencies for local runRun the service code locally (serving at http://localhost:3000 by default):
bentoml serveYou should expect to see the following output.
[INFO] [cli] Starting production HTTP BentoServer from "service:Summarization" listening on http://localhost:3000 (Press CTRL+C to quit)
[INFO] [entry_service:Summarization:1] Service Summarization initialized
Now you can run inference from your browser at http://localhost:3000 or with a Python script:
import bentoml
with bentoml.SyncHTTPClient('http://localhost:3000') as client:
summarized_text: str = client.summarize([bentoml.__doc__])[0]
print(f"Result: {summarized_text}")Run bentoml build to package necessary code, models, dependency configs into a Bento - the standardized deployable artifact in BentoML:
bentoml buildEnsure Docker is running. Generate a Docker container image for deployment:
bentoml containerize summarization:latestRun the generated image:
docker run --rm -p 3000:3000 summarization:latestBentoCloud provides compute infrastructure for rapid and reliable GenAI adoption. It helps speed up your BentoML development process leveraging cloud compute resources, and simplify how you deploy, scale and operate BentoML in production.
