Want to build a search system backed by deep learning? You've come to the right place!

Jina is the easiest way to build neural search in the cloud. It provides an one-stop solution for multi-/cross-modality search. Jina has long-term support from a full-time, venture-backed team.

⏱️ Time Saver - Bootstrapping an AI-powered search system with Jina takes just minutes, and saves engineers months of time!

🧠 First-class AI models - Jina is a new design pattern for neural search systems, offering first-class support for state-of-the-art AI models.

🌌 Universal Search - Large-scale indexing and querying data of any kind on multiple platforms. Video, image, long/short text, music, source code, you name it!

🚀 Production Ready - Cloud-native features come out-of-the-box, e.g. containerization, microservice, distributing, scaling, sharding, async IO, REST, gRPC.

🧩 Plug & Play - Extend Jina with simple Python scripts or Docker images optimized for your search domain. Check out Jina Hub for more extensions.

Install

Install from PyPi

On Linux/MacOS with Python >= 3.7:

pip install jina

To install Jina with extra dependencies, or install on Raspberry Pi please refer to the documentation.

...or Run in a Docker Container

We provide a universal Docker image that supports multiple architectures (including x64, x86, arm-64/v7/v6). Simply run:

docker run jinaai/jina --help

Jina "Hello, World!" 👋🌍

As a starter, you can try out our "Hello, World" - a simple demo of image neural search for Fashion-MNIST. No extra dependencies needed, just run:

jina hello-world

...or even easier for Docker users, no install required:

docker run -v "$(pwd)/j:/j" jinaai/jina hello-world --workdir /j && open j/hello-world.html  # replace "open" with "xdg-open" on Linux

Click here to see console output

The Docker image downloads the Fashion-MNIST training and test dataset and tells Jina to index 60,000 images from the training set. Then it randomly samples images from the test set as queries and asks Jina to retrieve relevant results. The whole process takes about 1 minute, and eventually opens a webpage and shows results like this:

The implementation behind it is as simple as can be:

Python API

or use YAML spec

or use Dashboard

from jina.flow import Flow

f = (Flow()
        .add(uses='encoder.yml', parallel=2)
        .add(uses='indexer.yml', shards=2, 
             separated_workspace=True))

with f:
    f.index(fashion_mnist, batch_size=1024)

!Flow
pods:
  encode:
    uses: encoder.yml
    parallel: 2
  index:
    uses: indexer.yml
    shards: 2
    separated_workspace: true

Adding Parallelism and Sharding

from jina.flow import Flow

f = (Flow().add(uses='encoder.yml', parallel=2)
           .add(uses='indexer.yml', shards=2, separated_workspace=True))

Distributing the Flow

from jina.flow import Flow

f = Flow().add(uses='encoder.yml', host='192.168.0.99')

Using a Docker Container

from jina.flow import Flow

f = (Flow().add(uses='jinahub/cnn-encode:0.1')
           .add(uses='jinahub/faiss-index:0.2', host='192.168.0.99'))

Concatenating Embeddings

from jina.flow import Flow

f = (Flow().add(name='eb1', uses='BiTImageEncoder')
           .add(name='eb2', uses='KerasImageEncoder', needs='gateway')
           .needs(['eb1', 'eb2'], uses='_concat'))

Enabling Network Queries

from jina.flow import Flow

f = Flow(port_expose=45678, rest_api=True)

with f:
    f.block()

Intrigued? Play with different options:

jina hello-world --help

Be sure to continue with our Jina 101 Guide - to understand all key concepts of Jina in 3 minutes!

Build your own Project

pip install cookiecutter && cookiecutter gh:jina-ai/cookiecutter-jina

With Cookiecutter you can easily create a Jina project from templates with one terminal command. This creates a Python entrypoint, YAML configs and a Dockerfile. You can start from there.
