A containerized REST API around OpenAI's CLIP model.

Last update: Nov 06, 2022

Overview

OpenAI's CLIP — REST API

This is a container wrapping OpenAI's CLIP model in a RESTful interface.

Running the container locally

First, build the container:

docker build -t clip-container:latest .

Then, you can run it:

docker run -it -p 8080:8080 --name "clip-container" --rm clip-container:latest /opt/ml/code/serve

Sending requests:

The container exposes two different endpoints:

GET /ping: Returns 200 status if the container is working properly.
POST /invocations: Processes a list of images and returns the list of labels with their corresponding probabilities.

Here is an example request assuming the container is listening in port 8080:

curl --location --request POST 'http://localhost:8080/invocations' \
--header 'Content-Type: application/json' \
--data-raw '{
    "images": [

    "classes": ["person", "bag", "person with a bag", "woman riding a horse", "woman with a bag", "woman with black shirt and a bag"]
}'

The response looks like this:

SageMaker Integration

This container is compatible with SageMaker so you should be able to host it as a SageMaker endpoint with no modifications. The code supports GPU and CPU instances.
