Velar Python SDK - Deploy ML models to GPUs with one command

Velar Python SDK

Deploy ML models to GPUs with one command.

Installation

pip install velar-sdk

Authentication

velar login

This opens your browser, signs you in, and saves an API key to ~/.velar/token automatically.

Quick Start

import velar

app = velar.App("my-model")

image = velar.Image.from_registry("pytorch/pytorch:2.1.0-cuda12.1-cudnn8-runtime")
image = image.pip_install("transformers", "accelerate")

@app.function(gpu="A100", image=image)
def run_inference(prompt: str) -> str:
    from transformers import pipeline
    pipe = pipeline("text-generation", model="gpt2")
    return pipe(prompt)[0]["generated_text"]

@app.local_entrypoint()
def main():
    result = run_inference.remote("Hello, world!")
    print(result)

Deploy:

velar deploy app:app

Run locally (calls the remote GPU):

velar run app:app

Image Builder

image = (
    velar.Image.from_registry("python:3.11-slim")
    .pip_install("torch", "transformers")
    .run_commands("apt-get update && apt-get install -y ffmpeg")
    .env(HF_HOME="/tmp/hf")
)
