git clone https://github.com/ultralytics/yolov5 # clone
cd yolov5
pip install -r requirements.txt # install
Environments
YOLOv5 may be run in any of the following up-to-date verified environments (with all dependencies including CUDA/CUDNN, Python and PyTorch preinstalled):
- Notebooks with free GPU:
- Google Cloud Deep Learning VM. See GCP Quickstart Guide
- Amazon Deep Learning AMI. See AWS Quickstart Guide

Status
If this badge is green, all YOLOv5 GitHub Actions Continuous Integration (CI) tests are currently passing. CI tests verify correct operation of YOLOv5 training, validation, inference, export and benchmarks on macOS, Windows, and Ubuntu every 24 hours and on every commit.
Introducing YOLOv8 π
We're excited to announce the launch of our latest state-of-the-art (SOTA) object detection model for 2023 - YOLOv8 π!
Designed to be fast, accurate, and easy to use, YOLOv8 is an ideal choice for a wide range of object detection, image segmentation and image classification tasks. With YOLOv8, you'll be able to quickly and accurately detect objects in real-time, streamline your workflows, and achieve new levels of accuracy in your projects.
Check out our YOLOv8 Docs for details and get started with:
pip install ultralytics
from yolov5.
@Powerfulidot hello,
Thank you for reaching out and for your interest in using YOLOv5 for your segmentation tasks!
To calculate metrics like mean Intersection over Union (mIoU) and mean Pixel Accuracy (mPA) for YOLOv5 segmentation (yolov5_seg
), you can follow these steps:
-
Update to the Latest Version: Ensure you are using the latest version of YOLOv5 from the Ultralytics repository and the latest version of
torch
. This ensures you have the latest features and bug fixes. -
Custom Evaluation Script: YOLOv5 does not natively include mIoU and mPA metrics in its validation script. However, you can modify the validation script to include these metrics. Below is an example of how you might calculate these metrics:
import torch
import numpy as np
from utils.metrics import ConfusionMatrix
def calculate_mIoU_mPA(preds, targets, num_classes):
cm = ConfusionMatrix(num_classes)
cm.process_batch(preds, targets)
iou = cm.iou()
mIoU = iou.mean().item()
mPA = (cm.tp / (cm.tp + cm.fn)).mean().item()
return mIoU, mPA
# Example usage during validation
# preds and targets should be tensors of shape [batch_size, height, width]
preds = torch.argmax(predictions, dim=1) # Assuming predictions are logits
mIoU, mPA = calculate_mIoU_mPA(preds, targets, num_classes=21) # Adjust num_classes as needed
print(f'mIoU: {mIoU}, mPA: {mPA}')
-
Integrate with YOLOv5 Validation: You can integrate the above function into the YOLOv5 validation loop. Modify the
val.py
script to include calls tocalculate_mIoU_mPA
and print or log the results. -
Comparative Experiments: Once you have integrated these metrics, you can run your validation and compare the results with other semantic segmentation algorithms like Unet and PSPNet.
If you encounter any issues or need further assistance, please provide a minimum reproducible code example so we can better understand and address your specific situation. You can find guidance on creating a minimum reproducible example here.
We hope this helps! If you have any more questions, feel free to ask. π
