inference-cpu 0.8.1

With no prior knowledge of machine learning or device-specific deployment, you can deploy a computer vision model to a range of devices and environments using Roboflow Inference.

👋 hello

Roboflow Inference is an opinionated tool for running inference on state-of-the-art computer vision models. With no prior knowledge of machine learning or device-specific deployment, you can deploy a computer vision model to a range of devices and environments. Inference supports object detection, classification, and instance segmentation models, and running foundation models (CLIP and SAM).

👩‍🏫 Examples

The /examples directory contains example code for working with and extending inference, including HTTP and UDP client code and an insights dashboard, along with community examples (PRs welcome)!

💻 Why Inference?

Inference provides a scalable method through which you can manage inferences for your vision projects.

Inference is backed by:

• A server, so you don’t have to reimplement things like image processing and prediction visualization on every project.

• Standardized APIs for computer vision tasks, so switching out the model weights and architecture can be done independently of your application code.

• Model architecture implementations, which implement the tensor parsing glue between images and predictions for supervised models that you've fine-tuned to perform custom tasks.

• A model registry, so your code can be independent from your model weights & you don't have to re-build and re-deploy every time you want to iterate on your model weights.

• Data management integrations, so you can collect more images of edge cases to improve your dataset & model the more it sees in the wild.

And more!

📌 Install pip vs Docker:

• pip: Installs inference into your Python environment. Lightweight, good for Python-centric projects.
• Docker: Packages inference with its environment. Ensures consistency across setups; ideal for scalable deployments.

💻 install

With ONNX CPU Runtime:

For CPU powered inference:

pip install inference

or

pip install inference-cpu

With ONNX GPU Runtime:

If you have an NVIDIA GPU, you can accelerate your inference with:

pip install inference-gpu

Without ONNX Runtime:

Roboflow Inference uses Onnxruntime as its core inference engine. Onnxruntime provides an array of different execution providers that can optimize inference on differnt target devices. If you decide to install onnxruntime on your own, install inference with:

pip install inference-core

Alternatively, you can take advantage of some advanced execution providers using one of our published docker images.

Extras:

Some functionality requires extra dependancies. These can be installed by specifying the desired extras during installation of Roboflow Inference.

extra	description
clip	Ability to use the core CLIP model (by OpenAI)
gaze	Ability to use the core Gaze model
http	Ability to run the http interface
sam	Ability to run the core Segment Anything model (by Meta AI)

Note: Both CLIP and Segment Anything require pytorch to run. These are included in their respective dependancies however pytorch installs can be highly environment dependant. See the official pytorch install page for instructions specific to your enviornment.

Example install with http dependancies:

pip install inference[http]

🔥 quickstart

Docker Quickstart:

import requests

dataset_id = "soccer-players-5fuqs"
version_id = "1"
image_url = "https://source.roboflow.com/pwYAXv9BTpqLyFfgQoPZ/u48G0UpWfk8giSw7wrU8/original.jpg"
#Replace ROBOFLOW_API_KEY with your Roboflow API Key
api_key = "ROBOFLOW_API_KEY"
confidence = 0.5

url = f"http://localhost:9001/{dataset_id}/{version_id}"

params = {
    "api_key": api_key,
    "confidence": confidence,
    "image": image_url,
}

res = requests.post(url, params=params)
print(res.json())

pip Quickstart:

After installing via pip, you can run a simple inference using:

from inference.models.utils import get_roboflow_model

model = get_roboflow_model(
    model_id="soccer-players-5fuqs/1", 
    #Replace ROBOFLOW_API_KEY with your Roboflow API Key
    api_key="ROBOFLOW_API_KEY"
)

results = model.infer(image="https://source.roboflow.com/pwYAXv9BTpqLyFfgQoPZ/u48G0UpWfk8giSw7wrU8/original.jpg", confidence=0.5, iou_threshold=0.5)

print(results)

CLIP Quickstart:

You can run inference with OpenAI's CLIP model using:

from inference.models import Clip

model = Clip(
    #Replace ROBOFLOW_API_KEY with your Roboflow API Key
    api_key = "ROBOFLOW_API_KEY"
)

image_url = "https://source.roboflow.com/7fLqS2r1SV8mm0YzyI0c/yy6hjtPUFFkq4yAvhkvs/original.jpg"

embeddings = model.embed_image(image_url)

print(embeddings)

SAM Quickstart:

You can run inference with Meta's Segment Anything model using:

from inference.models import SegmentAnything

model = SegmentAnything(
    #Replace ROBOFLOW_API_KEY with your Roboflow API Key
    api_key = "ROBOFLOW_API_KEY"
)

image_url = "https://source.roboflow.com/7fLqS2r1SV8mm0YzyI0c/yy6hjtPUFFkq4yAvhkvs/original.jpg"

embeddings = model.embed_image(image_url)

print(embeddings)

🏗️ inference process

To standardize the inference process throughout all our models, Roboflow Inference has a structure for processing inference requests. The specifics can be found on each model's respective page, but overall it works like this for most models:
