4.6 Train and Deploy Your Own Vision Model
Introduction
YOLO26 is the latest generation of the YOLO family, designed for real-time, edge-ready vision AI. It is built to be faster, lighter, and easier to deploy, while still delivering strong accuracy for tasks such as object detection, segmentation, classification, and pose estimation. Compared with earlier YOLO models, YOLO26 places a stronger focus on efficient deployment and end-to-end inference, which makes it especially suitable for edge devices and practical applications.

In this chapter, we will introduce how to quickly train and deploy your own advanced detection model on reComputer, so you can move from data to a working real-world AI application with an efficient and modern workflow.
Quick experience
Step 1: Define the Task Clearly
A strong project begins with a clear question.
Examples:
- detect helmets and persons
- detect occupied parking spaces
- detect pallets and forklifts
For the convenience of demonstration, we have provided a script that can assist us in completing the process from data collection to model deployment.
🚀Just give it a try and run it yourself!
cd 4.6-Train-and-Deploy-Your-Own-Vision-Model/code
python yolo_end_to_end.pyStep 2: Collect Data
Connect a camera to your device, select the target you want to detect, and collect the appropriate dataset images.

Step 3: Annotate the Data
For detection, annotation usually means drawing bounding boxes and assigning class labels.
Use our tool and drag the mouse to mark the target you want to detect.

Step 4: Train a Model
Split your datasets and select a pretrain model to train.
The training set is used to teach the model by adjusting its parameters. The validation set is used during development to check how well the model is generalizing, compare different settings, and decide when to stop training. In short, dataset splitting helps us train the model, improve the model, and evaluate the model in a trustworthy way.

Training is the stage where the model learns from the dataset and gradually improves its predictions. Usually, we begin with a starting checkpoint, which means using a pretrained model instead of starting from zero. This helps the model learn faster and often gives better results.
Step 5: Inference
Select the model weights that have been trained previously and observe its performance.

Note : If you want your model to perform better, you need to increase your dataset or perform data augmentation operations.
Common Misunderstandings
- "A high metric always means the model is ready."
- Real-world testing is still necessary.
- "More data automatically means a better model."
- More data helps only if it is relevant and well labeled.
- "If training finishes, deployment is easy."
- Deployment introduces speed, memory, and system constraints.
Exercises / Reflection
- Design a two-class object detection project that could be completed by a beginner.
- List five types of scene variation you would want in the dataset.
- Explain the difference between validation results and real deployment performance.
- After running a training job, inspect three failure cases and describe what kind of data might fix them.
Summary
Training a custom vision model is not only about running a command. It is a data-driven process involving task definition, annotation, training, validation, and error analysis. In the next section, we move from the first successful model to export and edge deployment.
