What is MLflow?

MLflow is an open-source platform developed by Databricks for managing the end-to-end machine learning lifecycle. It includes tools for tracking experiments, packaging code into reproducible runs, and sharing and deploying models. MLflow is designed to work with any machine learning library and programming language.

Features

• Metrics Logging: Logs metrics at the end of each epoch and at the end of the training.
• Parameter Logging: Logs all the parameters used in the training.
• Artifacts Logging: Logs model artifacts, including weights and configuration files, at the end of the training.

Setup and Prerequisites

Ensure MLflow is installed. If not, install it using pip:

pip install mlflow

Make sure that MLflow logging is enabled in Ultralytics settings. Usually, this is controlled by the settings mflow key. See the settings page for more info.

!!! Example "Update Ultralytics MLflow Settings"

=== "Python"

    Within the Python environment, call the `update` method on the `settings` object to change your settings:
    ```py
    from ultralytics import settings

    # Update a setting
    settings.update({"mlflow": True})

    # Reset settings to default values
    settings.reset()
    ```

=== "CLI"

    If you prefer using the command-line interface, the following commands will allow you to modify your settings:
    ```py
    # Update a setting
    yolo settings runs_dir='/path/to/runs'

    # Reset settings to default values
    yolo settings reset
    ```

    ```py
    from deepsparse import Pipeline

    # Specify the path to your YOLOv8 ONNX model
    model_path = "path/to/yolov8n.onnx"

    # Set up the DeepSparse Pipeline
    yolo_pipeline = Pipeline.create(task="yolov8", model_path=model_path)

    # Run the model on your images
    images = ["path/to/image.jpg"]
    pipeline_outputs = yolo_pipeline(images=images)
    ```

Step 4: Benchmarking Performance

It's important to check that your YOLOv8 model is performing optimally on DeepSparse. You can benchmark your model's performance to analyze throughput and latency:

!!! Tip "Benchmarking"

=== "CLI"

    ```py
    # Benchmark performance
    deepsparse.benchmark model_path="path/to/yolov8n.onnx" --scenario=sync --input_shapes="[1,3,640,640]"
    ```

Step 5: Additional Features

DeepSparse provides additional features for practical integration of YOLOv8 in applications, such as image annotation and dataset evaluation.

!!! Tip "Additional Features"

=== "CLI"

    ```py
    # For image annotation
    deepsparse.yolov8.annotate --source "path/to/image.jpg" --model_filepath "path/to/yolov8n.onnx"

    # For evaluating model performance on a dataset
    deepsparse.yolov8.eval --model_path "path/to/yolov8n.onnx"
    ```

ONNX and ONNX Runtime

ONNX, which stands for Open Neural Network Exchange, is a community project that Facebook and Microsoft initially developed. The ongoing development of ONNX is a collaborative effort supported by various organizations like IBM, Amazon (through AWS), and Google. The project aims to create an open file format designed to represent machine learning models in a way that allows them to be used across different AI frameworks and hardware.

ONNX models can be used to transition between different frameworks seamlessly. For instance, a deep learning model trained in PyTorch can be exported to ONNX format and then easily imported into TensorFlow.

Alternatively, ONNX models can be used with ONNX Runtime. ONNX Runtime is a versatile cross-platform accelerator for machine learning models that is compatible with frameworks like PyTorch, TensorFlow, TFLite, scikit-learn, etc.

ONNX Runtime optimizes the execution of ONNX models by leveraging hardware-specific capabilities. This optimization allows the models to run efficiently and with high performance on various hardware platforms, including CPUs, GPUs, and specialized accelerators.

Whether used independently or in tandem with ONNX Runtime, ONNX provides a flexible solution for machine learning model deployment and compatibility.

Key Features of ONNX Models

The ability of ONNX to handle various formats can be attributed to the following key features:

• Common Model Representation: ONNX defines a common set of operators (like convolutions, layers, etc.) and a standard data format. When a model is converted to ONNX format, its architecture and weights are translated into this common representation. This uniformity ensures that the model can be understood by any framework that supports ONNX.

• Versioning and Backward Compatibility: ONNX maintains a versioning system for its operators. This ensures that even as the standard evolves, models created in older versions remain usable. Backward compatibility is a crucial feature that prevents models from becoming obsolete quickly.

• Graph-based Model Representation: ONNX represents models as computational graphs. This graph-based structure is a universal way of representing machine learning models, where nodes represent operations or computations, and edges represent the tensors flowing between them. This format is easily adaptable to various frameworks which also represent models as graphs.

• Tools and Ecosystem: There is a rich ecosystem of tools around ONNX that assist in model conversion, visualization, and optimization. These tools make it easier for developers to work with ONNX models and to convert models between different frameworks seamlessly.

In this guide, we are going to showcase how to find, label, and organize data for use in training a custom Ultralytics YOLOv8 model. Use the table of contents below to jump directly to a specific section:

• Gather data for training a custom YOLOv8 model
• Upload, convert and label data for YOLOv8 format
• Pre-process and augment data for model robustness
• Dataset management for YOLOv8
• Export data in 40+ formats for model training
• Upload custom YOLOv8 model weights for testing and deployment
• Gather Data for Training a Custom YOLOv8 Model

Roboflow provides two services that can help you collect data for YOLOv8 models: Universe and Collect.

Universe is an online repository with over 250,000 vision datasets totalling over 100 million images.

With a free Roboflow account, you can export any dataset available on Universe. To export a dataset, click the "Download this Dataset" button on any dataset.

For YOLOv8, select "YOLOv8" as the export format:

Universe also has a page that aggregates all public fine-tuned YOLOv8 models uploaded to Roboflow. You can use this page to explore pre-trained models you can use for testing or for automated data labeling or to prototype with Roboflow inference.

If you want to gather images yourself, try Collect, an open source project that allows you to automatically gather images using a webcam on the edge. You can use text or image prompts with Collect to instruct what data should be collected, allowing you to capture only the useful data you need to build your vision model.

Upload, Convert and Label Data for YOLOv8 Format

Roboflow Annotate is an online annotation tool for use in labeling images for object detection, classification, and segmentation.

To label data for a YOLOv8 object detection, instance segmentation, or classification model, first create a project in Roboflow.

Next, upload your images, and any pre-existing annotations you have from other tools (using one of the 40+ supported import formats), into Roboflow.

Select the batch of images you have uploaded on the Annotate page to which you are taken after uploading images. Then, click "Start Annotating" to label images.

To label with bounding boxes, press the B key on your keyboard or click the box icon in the sidebar. Click on a point where you want to start your bounding box, then drag to create the box:

A pop-up will appear asking you to select a class for your annotation once you have created an annotation.

To label with polygons, press the P key on your keyboard, or the polygon icon in the sidebar. With the polygon annotation tool enabled, click on individual points in the image to draw a polygon.

Roboflow offers a SAM-based label assistant with which you can label images faster than ever. SAM (Segment Anything Model) is a state-of-the-art computer vision model that can precisely label images. With SAM, you can significantly speed up the image labeling process. Annotating images with polygons becomes as simple as a few clicks, rather than the tedious process of precisely clicking points around an object.

To use the label assistant, click the cursor icon in the sidebar, SAM will be loaded for use in your project.

Hover over any object in the image and SAM will recommend an annotation. You can hover to find the right place to annotate, then click to create your annotation. To amend your annotation to be more or less specific, you can click inside or outside the annotation SAM has created on the document.

You can also add tags to images from the Tags panel in the sidebar. You can apply tags to data from a particular area, taken from a specific camera, and more. You can then use these tags to search through data for images matching a tag and generate versions of a dataset with images that contain a particular tag or set of tags.

Models hosted on Roboflow can be used with Label Assist, an automated annotation tool that uses your YOLOv8 model to recommend annotations. To use Label Assist, first upload a YOLOv8 model to Roboflow (see instructions later in the guide). Then, click the magic wand icon in the left sidebar and select your model for use in Label Assist.

Choose a model, then click "Continue" to enable Label Assist:

When you open new images for annotation, Label Assist will trigger and recommend annotations.

Dataset Management for YOLOv8

Roboflow provides a suite of tools for understanding computer vision datasets.

First, you can use dataset search to find images that meet a semantic text description (i.e. find all images that contain people), or that meet a specified label (i.e. the image is associated with a specific tag). To use dataset search, click "Dataset" in the sidebar. Then, input a search query using the search bar and associated filters at the top of the page.

For example, the following text query finds images that contain people in a dataset:

You can narrow your search to images with a particular tag using the "Tags" selector:

Before you start training a model with your dataset, we recommend using Roboflow Health Check, a web tool that provides an insight into your dataset and how you can improve the dataset prior to training a vision model.

To use Health Check, click the "Health Check" sidebar link. A list of statistics will appear that show the average size of images in your dataset, class balance, a heatmap of where annotations are in your images, and more.

Health Check may recommend changes to help enhance dataset performance. For example, the class balance feature may show that there is an imbalance in labels that, if solved, may boost performance or your model.

Export Data in 40+ Formats for Model Training

To export your data, you will need a dataset version. A version is a state of your dataset frozen-in-time. To create a version, first click "Versions" in the sidebar. Then, click the "Create New Version" button. On this page, you will be able to choose augmentations and preprocessing steps to apply to your dataset:

For each augmentation you select, a pop-up will appear allowing you to tune the augmentation to your needs. Here is an example of tuning a brightness augmentation within specified parameters:

When your dataset version has been generated, you can export your data into a range of formats. Click the "Export Dataset" button on your dataset version page to export your data:

You are now ready to train YOLOv8 on a custom dataset. Follow this written guide and YouTube video for step-by-step instructions or refer to the Ultralytics documentation.

Upload Custom YOLOv8 Model Weights for Testing and Deployment

Roboflow offers an infinitely scalable API for deployed models and SDKs for use with NVIDIA Jetsons, Luxonis OAKs, Raspberry Pis, GPU-based devices, and more.

You can deploy YOLOv8 models by uploading YOLOv8 weights to Roboflow. You can do this in a few lines of Python code. Create a new Python file and add the following code:

import roboflow  # install with 'pip install roboflow'

roboflow.login()

rf = roboflow.Roboflow()

project = rf.workspace(WORKSPACE_ID).project("football-players-detection-3zvbc")
dataset = project.version(VERSION).download("yolov8")

project.version(dataset.version).deploy(model_type="yolov8", model_path=f"{HOME}/runs/detect/train/")

In this code, replace the project ID and version ID with the values for your account and project. Learn how to retrieve your Roboflow API key.

When you run the code above, you will be asked to authenticate. Then, your model will be uploaded and an API will be created for your project. This process can take up to 30 minutes to complete.

To test your model and find deployment instructions for supported SDKs, go to the "Deploy" tab in the Roboflow sidebar. At the top of this page, a widget will appear with which you can test your model. You can use your webcam for live testing or upload images or videos.

You can also use your uploaded model as a labeling assistant. This feature uses your trained model to recommend annotations on images uploaded to Roboflow.

How to Evaluate YOLOv8 Models

Roboflow provides a range of features for use in evaluating models.

Once you have uploaded a model to Roboflow, you can access our model evaluation tool, which provides a confusion matrix showing the performance of your model as well as an interactive vector analysis plot. These features can help you find opportunities to improve your model.

To access a confusion matrix, go to your model page on the Roboflow dashboard, then click "View Detailed Evaluation":

A pop-up will appear showing a confusion matrix:

Hover over a box on the confusion matrix to see the value associated with the box. Click on a box to see images in the respective category. Click on an image to view the model predictions and ground truth data associated with that image.

For more insights, click Vector Analysis. This will show a scatter plot of the images in your dataset, calculated using CLIP. The closer images are in the plot, the more similar they are, semantically. Each image is represented as a dot with a color between white and red. The more red the dot, the worse the model performed.

You can use Vector Analysis to:

• Find clusters of images;
• Identify clusters where the model performs poorly, and;
• Visualize commonalities between images on which the model performs poorly.
