YOLO Object Detection: Image Recognition Software Guide

Introduction

YOLO (You Only Look Once) is a popular object detection algorithm well-documented by Ultralytics. For more comprehensive details, visit the Ultralytics YOLO documentation.

Docker Ultralytics

To perform object detection using YOLO in a Docker environment, you can run the following commands:

# Install
docker pull ultralytics/ultralytics

# Run YOLO prediction on a remote image
docker run -v ./runs:/usr/src/ultralytics/runs ultralytics/ultralytics yolo predict model=yolov8n.pt source=https://ultralytics.com/images/bus.jpg

# View result
open runs/detect/predict/bus.jpg

# Run YOLO prediction on a locally saved image
docker run -v ./runs:/usr/src/ultralytics/runs ultralytics/ultralytics yolo predict model=yolov8n.pt source=./runs/detect/predict/bus.jpg

# View result
open runs/detect/predict2/bus.jpg

Quick 60-Second Installation and Usage for Object Detection

Follow these steps to quickly install and use YOLO for object detection:

1. Create a Python Virtual Environment:

python3 -m venv venv
source venv/bin/activate

2. Install Required Dependencies:

# Option 1: Specific Torch and Torchaudio versions
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2

# Option 2: Alternative versions
pip install torch==2.2.2 torchvision==0.17.2 torchaudio==2.2.2

3. Install Ultralytics:

pip install ultralytics

4. Verify Torch Installation:

pip show torch

5. Run YOLO Prediction:

yolo predict model=yolov8n.pt source='https://ultralytics.com/images/bus.jpg'

6. Open the Resulting Image:

open runs/detect/predict/bus.jpg

Python Code Usage

You can find the Python code to perform YOLO predictions in the Ultralytics documentation.

from ultralytics import YOLO

# Load a model
model = YOLO("yolov8n.pt")  # load an official model
#### model = YOLO("path/to/best.pt")  # load a custom model

# Predict with the model
results = model("https://ultralytics.com/images/bus.jpg")  # predict on an image

Detectron2

Detectron2, another object detection tool, has a lot of promise. However it's not been kept up to date. For more information, visit Meta's AI Detectron2 page.
