Github PK Tool:Github PK Tool

Status: Experimental 🧪

Easily deploy GPU models as serverless APIs

  • Deploy an API from a template
$ kuda deploy -f https://github.com/cyrildiagne/kuda/releases/download/v0.4.0-preview/example-hello-gpu.yaml
  • Call it!
$ curl https://hello-gpu.default.$your_domain
Hello GPU!

Serverless GPU inference

Kuda builds on Knative to allocate cloud GPUs only when there is traffic.

This is ideal when you want to share ML projects online without keeping expensive GPUs allocated all the time.

Turn any model into a serverless API

Kuda deploys APIs as containers, so you can use any language, any framework, and there is no library to import in your code.

All you need is a Dockerfile.

Here's a minimal example that just prints the result of nvidia-smi using Flask:

  • main.py
import os
import flask

app = flask.Flask(__name__)

@app.route('/')
def hello():
    return 'Hello GPU:\n' + os.popen('nvidia-smi').read()
  • Dockerfile
FROM nvidia/cuda:10.1-base

RUN apt-get install -y python3 python3-pip

RUN pip3 install setuptools Flask gunicorn

COPY main.py ./main.py

CMD exec gunicorn --bind :80 --workers 1 --threads 8 main:app
  • kuda.yaml
name: hello-gpu
deploy:
  dockerfile: ./Dockerfile

Running kuda deploy in this example would build and deploy the API to a url such as https://hello-gpu.my-namespace.example.com.

Checkout the full example with annotations in examples/hello-gpu-flask.

Features

  • Provision GPUs & scale based on traffic (from zero to N)
  • Interactive development on cloud GPUs from any workstation
  • Protect & control access to your APIs using API Keys
  • HTTPS with TLS termination & automatic certificate management
