👋 hello

Roboflow Inference is an open-source platform designed to simplify the deployment of computer vision models. It enables developers to perform object detection, classification, and instance segmentation and utilize foundation models like CLIP, Segment Anything, and YOLO-World through a Python-native package, a self-hosted inference server, or a fully managed API.

Explore our enterprise options for advanced features like server deployment, active learning, and commercial licenses for YOLOv5 and YOLOv8.

💻 install

Inference package requires Python>=3.8,<=3.11. Click here to learn more about running Inference inside Docker.

pip install inference

👉 additional considerations

• hardware

  Enhance model performance in GPU-accelerated environments by installing CUDA-compatible dependencies.

  pip install inference-gpu
  

• models

  The inference and inference-gpu packages install only the minimal shared dependencies. Install model-specific dependencies to ensure code compatibility and license compliance. Learn more about the models supported by Inference.

  pip install inference[yolo-world]
  

🔥 quickstart

Use Inference SDK to run models locally with just a few lines of code. The image input can be a URL, a numpy array (BGR), or a PIL image.

from inference import get_model

model = get_model(model_id="yolov8n-640")

results = model.infer("https://media.roboflow.com/inference/people-walking.jpg")

👉 roboflow models

Set up your ROBOFLOW_API_KEY to access thousands of fine-tuned models shared by the Roboflow Universe community and your custom model. Navigate to 🔑 keys section to learn more.

from inference import get_model

model = get_model(model_id="soccer-players-5fuqs/1")

results = model.infer(
    image="https://media.roboflow.com/inference/soccer.jpg",
    confidence=0.5,
    iou_threshold=0.5
)

👉 foundational models

• CLIP Embeddings - generate text and image embeddings that you can use for zero-shot classification or assessing image similarity.

  from inference.models import Clip
  
  model = Clip()
  
  embeddings_text = clip.embed_text("a football match")
  embeddings_image = model.embed_image("https://media.roboflow.com/inference/soccer.jpg")
  

• Segment Anything - segment all objects visible in the image or only those associated with selected points or boxes.

  from inference.models import SegmentAnything
  
  model = SegmentAnything()
  
  result = model.segment_image("https://media.roboflow.com/inference/soccer.jpg")
  

• YOLO-World - an almost real-time zero-shot detector that enables the detection of any objects without any training.

  from inference.models import YOLOWorld
  
  model = YOLOWorld(model_id="yolo_world/l")
  
  result = model.infer(
      image="https://media.roboflow.com/inference/dog.jpeg",
      text=["person", "backpack", "dog", "eye", "nose", "ear", "tongue"],
      confidence=0.03
  )
  

📟 inference server

• deploy server

  The inference server is distributed via Docker. Behind the scenes, inference will download and run the image that is appropriate for your hardware. Here, you can learn more about the supported images.

  inference server start
  

• run client

  Consume inference server predictions using the HTTP client available in the Inference SDK.

  from inference_sdk import InferenceHTTPClient
  
  client = InferenceHTTPClient(
      api_url="http://localhost:9001",
      api_key=<ROBOFLOW_API_KEY>
  )
  with client.use_model(model_id="soccer-players-5fuqs/1"):
      predictions = client.infer("https://media.roboflow.com/inference/soccer.jpg")
  

  If you're using the hosted API, change the local API URL to https://detect.roboflow.com. Accessing the hosted inference server and/or using any of the fine-tuned models require a ROBOFLOW_API_KEY. For further information, visit the 🔑 keys section.

🎥 inference pipeline

The inference pipeline is an efficient method for processing static video files and streams. Select a model, define the video source, and set a callback action. You can choose from predefined callbacks that allow you to display results on the screen or save them to a file.

from inference import InferencePipeline
from inference.core.interfaces.stream.sinks import render_boxes

pipeline = InferencePipeline.init(
    model_id="yolov8x-1280",
    video_reference="https://media.roboflow.com/inference/people-walking.mp4",
    on_prediction=render_boxes
)

pipeline.start()
pipeline.join()

🔑 keys

Inference enables the deployment of a wide range of pre-trained and foundational models without an API key. To access thousands of fine-tuned models shared by the Roboflow Universe community, configure your API key.

export ROBOFLOW_API_KEY=<YOUR_API_KEY>
