# Advanced YOLOv8 Experiment Tracking with DVCLive
Experiment tracking in machine learning is critical to model development and evaluation. It involves recording and analyzing various parameters, metrics, and outcomes from numerous training runs. This process is essential for understanding model performance and making data-driven decisions to refine and optimize models.
Integrating DVCLive with [Ultralytics YOLOv8](https://ultralytics.com) transforms the way experiments are tracked and managed. This integration offers a seamless solution for automatically logging key experiment details, comparing results across different runs, and visualizing data for in-depth analysis. In this guide, we'll understand how DVCLive can be used to streamline the process.
## DVCLive
[DVCLive](https://dvc.org/doc/dvclive), developed by DVC, is an innovative open-source tool for experiment tracking in machine learning. Integrating seamlessly with Git and DVC, it automates the logging of crucial experiment data like model parameters and training metrics. Designed for simplicity, DVCLive enables effortless comparison and analysis of multiple runs, enhancing the efficiency of machine learning projects with intuitive data visualization and analysis tools.
## YOLOv8 Training with DVCLive
YOLOv8 training sessions can be effectively monitored with DVCLive. Additionally, DVC provides integral features for visualizing these experiments, including the generation of a report that enables the comparison of metric plots across all tracked experiments, offering a comprehensive view of the training process.
## Installation
To install the required packages, run:
!!! Tip "Installation"
=== "CLI"
```bash
# Install the required packages for YOLOv8 and DVCLive
pip install ultralytics dvclive
```
For detailed instructions and best practices related to the installation process, be sure to check our [YOLOv8 Installation guide](../quickstart.md). While installing the required packages for YOLOv8, if you encounter any difficulties, consult our [Common Issues guide](../guides/yolo-common-issues.md) for solutions and tips.
## Configuring DVCLive
Once you have installed the necessary packages, the next step is to set up and configure your environment with the necessary credentials. This setup ensures a smooth integration of DVCLive into your existing workflow.
Begin by initializing a Git repository, as Git plays a crucial role in version control for both your code and DVCLive configurations.
!!! Tip "Initial Environment Setup"
=== "CLI"
```bash
# Initialize a Git repository
git init -q
# Configure Git with your details
git config --local user.email "you@example.com"
git config --local user.name "Your Name"
# Initialize DVCLive in your project
dvc init -q
# Commit the DVCLive setup to your Git repository
git commit -m "DVC init"
```
In these commands, ensure to replace "you@example.com" with the email address associated with your Git account, and "Your Name" with your Git account username.
## Usage
Before diving into the usage instructions, be sure to check out the range of [YOLOv8 models offered by Ultralytics](../models/index.md). This will help you choose the most appropriate model for your project requirements.
### Training YOLOv8 Models with DVCLive
Start by running your YOLOv8 training sessions. You can use different model configurations and training parameters to suit your project needs. For instance:
```bash
# Example training commands for YOLOv8 with varying configurations
yolo train model=yolov8n.pt data=coco8.yaml epochs=5 imgsz=512
yolo train model=yolov8n.pt data=coco8.yaml epochs=5 imgsz=640
```
Adjust the model, data, epochs, and imgsz parameters according to your specific requirements. For a detailed understanding of the model training process and best practices, refer to our [YOLOv8 Model Training guide](../modes/train.md).
### Monitoring Experiments with DVCLive
DVCLive enhances the training process by enabling the tracking and visualization of key metrics. When installed, Ultralytics YOLOv8 automatically integrates with DVCLive for experiment tracking, which you can later analyze for performance insights. For a comprehensive understanding of the specific performance metrics used during training, be sure to explore [our detailed guide on performance metrics](../guides/yolo-performance-metrics.md).
### Analyzing Results
After your YOLOv8 training sessions are complete, you can leverage DVCLive's powerful visualization tools for in-depth analysis of the results. DVCLive's integration ensures that all training metrics are systematically logged, facilitating a comprehensive evaluation of your model's performance.
To start the analysis, you can extract the experiment data using DVC's API and process it with Pandas for easier handling and visualization:
```python
import dvc.api
import pandas as pd
# Define the columns of interest
columns = ["Experiment", "epochs", "imgsz", "model", "metrics.mAP50-95(B)"]
# Retrieve experiment data
df = pd.DataFrame(dvc.api.exp_show(), columns=columns)
# Clean the data
df.dropna(inplace=True)
df.reset_index(drop=True, inplace=True)
# Display the DataFrame
print(df)
```
The output of the code snippet above provides a clear tabular view of the different experiments conducted with YOLOv8 models. Each row represents a different training run, detailing the experiment's name, the number of epochs, image size (imgsz), the specific model used, and the mAP50-95(B) metric. This metric is crucial for evaluating the model's accuracy, with higher values indicating better performance.
#### Visualizing Results with Plotly
For a more interactive and visual analysis of your experiment results, you can use Plotly's parallel coordinates plot. This type of plot is particularly useful for understanding the relationships and trade-offs between different parameters and metrics.
```python
from plotly.express import parallel_coordinates
# Create a parallel coordinates plot
fig = parallel_coordinates(df, columns, color="metrics.mAP50-95(B)")
# Display the plot
fig.show()
```
The output of the code snippet above generates a plot that will visually represent the relationships between epochs, image size, model type, and their corresponding mAP50-95(B) scores, enabling you to spot trends and patterns in your experiment data.
#### Generating Comparative Visualizations with DVC
DVC provides a useful command to generate comparative plots for your experiments. This can be especially helpful to compare the performance of different models over various training runs.
```bash
# Generate DVC comparative plots
dvc plots diff $(dvc exp list --names-only)
```
After executing this command, DVC generates plots comparing the metrics across different experiments, which are saved as HTML files. Below is an example image illustrating typical plots generated by this process. The image showcases various graphs, including those representing mAP, recall, precision, loss values, and more, providing a visual overview of key performance metrics:
### Displaying DVC Plots
If you are using a Jupyter Notebook and you want to display the generated DVC plots, you can use the IPython display functionality.
```python
from IPython.display import HTML
# Display the DVC plots as HTML
HTML(filename='./dvc_plots/index.html')
```
This code will render the HTML file containing the DVC plots directly in your Jupyter Notebook, providing an easy and convenient way to analyze the visualized experiment data.
### Making Data-Driven Decisions
Use the insights gained from these visualizations to make informed decisions about model optimizations, hyperparameter tuning, and other modifications to enhance your model's performance.
### Iterating on Experiments
Based on your analysis, iterate on your experiments. Adjust model configurations, training parameters, or even the data inputs, and repeat the training and analysis process. This iterative approach is key to refining your model for the best possible performance.
