Description

gibbs is a python package that helps you scale your ML workers (or any python code) across processes and machines, asynchronously.

gibbs is :

• ⚡️ Highly performant
• 🔀 Asynchronous
• 🐥 Easy-to-use

Install

Install gibbs by running :

pip install gibbs

Usage

After defining your awesome model :

import time

class MyAwesomeModel:
    def __init__(self, wait_time=0.25):
        super().__init__()
        self.w = wait_time

    def __call__(self, x):
        time.sleep(self.w)
        return x**2

You can simply start a few workers serving the model :

from gibbs import Worker

for _ in range(4):
    Worker(MyAwesomeModel).start()

And send requests through the Hub :

from gibbs import Hub

hub = Hub()

# In an async function
await hub.request(34)

And that's it !

Make sure to check the documentation for a more detailed explanation.

Or you can run some examples from the examples/ folder.

FAQ

❓ How gibbs works ?

gibbs simply run your model code in separate processes, and send requests to the right process to ensure requests are treated in parallel.

gibbs uses a modified form of the Paranoid Pirate Pattern from the zmq guide.

❓ Why the name "gibbs" ?

Joshamee Gibbs is the devoted first mate of Captain Jack Sparrow.
Since we are using the Paranoid Pirate Pattern, we needed a pirate name !

---

Then you can just try to commit your code. If you code does not meet the quality required by linters, it will not be committed. You can just fix your code and try to commit again !
