Each badge shows the status of the last run of the corresponding CI test on the `main` branch of the respective repository. If a test fails, the badge will display a "failing" status, and if it passes, it will display a "passing" status.
If you notice a test failing, it would be a great help if you could report it through a GitHub issue in the respective repository.
Remember, a successful CI test does not mean that everything is perfect. It is always recommended to manually review the code before deployment or merging changes.
## Code Coverage
Code coverage is a metric that represents the percentage of your codebase that is executed when your tests run. It provides insight into how well your tests exercise your code and can be crucial in identifying untested parts of your application. A high code coverage percentage is often associated with a lower likelihood of bugs. However, it's essential to understand that code coverage does not guarantee the absence of defects. It merely indicates which parts of the code have been executed by the tests.
### Integration with [codecov.io](https://codecov.io/)
At Ultralytics, we have integrated our repositories with [codecov.io](https://codecov.io/), a popular online platform for measuring and visualizing code coverage. Codecov provides detailed insights, coverage comparisons between commits, and visual overlays directly on your code, indicating which lines were covered.
By integrating with Codecov, we aim to maintain and improve the quality of our code by focusing on areas that might be prone to errors or need further testing.

!!! Example "Example Docstrings"
=== "Google-style"
This example illustrates a Google-style docstring. Ensure that both input and output `types` are always enclosed in parentheses, e.g., `(bool)`.
```python
def example_function(arg1, arg2=4):
"""
Example function demonstrating Google-style docstrings.
Args:
arg1 (int): The first argument.
arg2 (int): The second argument, with a default value of 4.
Returns:
(bool): True if successful, False otherwise.
Examples:
>>> result = example_function(1, 2) # returns False
"""
if arg1 == arg2:
return True
return False
```
=== "Google-style with type hints"
This example includes both a Google-style docstring and type hints for arguments and returns, though using either independently is also acceptable.
```python
def example_function(arg1: int, arg2: int = 4) -> bool:
"""
Example function demonstrating Google-style docstrings.
Args:
arg1: The first argument.
arg2: The second argument, with a default value of 4.
Returns:
True if successful, False otherwise.
Examples:
>>> result = example_function(1, 2) # returns False
"""
if arg1 == arg2:
return True
return False
```
=== "Single-line"
For smaller or simpler functions, a single-line docstring may be sufficient. The docstring must use three double-quotes, be a complete sentence, start with a capital letter, and end with a period.
```python
def example_small_function(arg1: int, arg2: int = 4) -> bool:
"""Example function with a single-line docstring."""
return arg1 == arg2
```

# Creating a Minimum Reproducible Example for Bug Reports in Ultralytics YOLO Repositories
When submitting a bug report for [Ultralytics](https://ultralytics.com) [YOLO](https://github.com/ultralytics) repositories, it's essential to provide a [Minimum Reproducible Example (MRE)](https://stackoverflow.com/help/minimal-reproducible-example). An MRE is a small, self-contained piece of code that demonstrates the problem you're experiencing. Providing an MRE helps maintainers and contributors understand the issue and work on a fix more efficiently. This guide explains how to create an MRE when submitting bug reports to Ultralytics YOLO repositories.
## 1. Isolate the Problem
The first step in creating an MRE is to isolate the problem. Remove any unnecessary code or dependencies that are not directly related to the issue. Focus on the specific part of the code that is causing the problem and eliminate any irrelevant sections.
## 2. Use Public Models and Datasets
When creating an MRE, use publicly available models and datasets to reproduce the issue. For example, use the `yolov8n.pt` model and the `coco8.yaml` dataset. This ensures that the maintainers and contributors can easily run your example and investigate the problem without needing access to proprietary data or custom models.
## 3. Include All Necessary Dependencies
Ensure all necessary dependencies are included in your MRE. If your code relies on external libraries, specify the required packages and their versions. Ideally, list the dependencies in your bug report using `yolo checks` if you have `ultralytics` installed or `pip list` for other tools.
## 4. Write a Clear Description of the Issue
Provide a clear and concise description of the issue you're experiencing. Explain the expected behavior and the actual behavior you're encountering. If applicable, include any relevant error messages or logs.
## 5. Format Your Code Properly
Format your code properly using code blocks in the issue description. This makes it easier for others to read and understand your code. In GitHub, you can create a code block by wrapping your code with triple backticks (\```) and specifying the language:
````bash
```python
# Your Python code goes here
```
````
## 6. Test Your MRE
Before submitting your MRE, test it to ensure that it accurately reproduces the issue. Make sure that others can run your example without any issues or modifications.
## Example of an MRE
Here's an example of an MRE for a hypothetical bug report:
**Bug description:**
When running inference on a 0-channel image, I get an error related to the dimensions of the input tensor.
**MRE:**
```python
import torch
from ultralytics import YOLO
# Load the model
model = YOLO("yolov8n.pt")
# Load a 0-channel image
image = torch.rand(1, 0, 640, 640)
# Run the model
results = model(image)
```
**Error message:**
```
RuntimeError: Expected input[1, 0, 640, 640] to have 3 channels, but got 0 channels instead
```
**Dependencies:**
- `torch==2.3.0`
- `ultralytics==8.2.0`
In this example, the MRE demonstrates the issue with a minimal amount of code, uses a public model (`"yolov8n.pt"`), includes all necessary dependencies, and provides a clear description of the problem along with the error message.
By following these guidelines, you'll help the maintainers and [contributors](https://github.com/ultralytics/ultralytics/graphs/contributors) of Ultralytics YOLO repositories to understand and resolve your issue more efficiently.
## FAQ
### How do I create an effective Minimum Reproducible Example (MRE) for bug reports in Ultralytics YOLO repositories?
To create an effective Minimum Reproducible Example (MRE) for bug reports in Ultralytics YOLO repositories, follow these steps:
1. **Isolate the Problem**: Remove any code or dependencies that are not directly related to the issue.
2. **Use Public Models and Datasets**: Utilize public resources like `yolov8n.pt` and `coco8.yaml` for easier reproducibility.
3. **Include All Necessary Dependencies**: Specify required packages and their versions. You can list dependencies using `yolo checks` if you have `ultralytics` installed or `pip list`.
4. **Write a Clear Description of the Issue**: Explain the expected and actual behavior, including any error messages or logs.
5. **Format Your Code Properly**: Use code blocks to format your code, making it easier to read.
6. **Test Your MRE**: Ensure your MRE reproduces the issue without modifications.
For a detailed guide, see [Creating a Minimum Reproducible Example](#creating-a-minimum-reproducible-example-for-bug-reports-in-ultralytics-yolo-repositories).
