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.
@Aq114 hello,
Thank you for reaching out and for providing detailed information about your issue. It sounds like you've encountered a KeyError
during inference with a model trained on Ultralytics HUB. Let's address this step-by-step.
KeyError Issue
The KeyError: 5059
suggests that the model is trying to access a class index that doesn't exist in the names
list. This can happen if there is a mismatch between the class indices in your dataset and the model's configuration.
Steps to Resolve
-
Verify Class Names: Ensure that the class names in your dataset match those expected by the model. You can check the
data.yaml
file used during training to confirm the class names and indices. -
Update to Latest Versions: Make sure you are using the latest versions of YOLOv5 and PyTorch. This can resolve many issues related to compatibility and bugs.
pip install --upgrade torch git pull https://github.com/ultralytics/yolov5
-
Reproduce the Issue: If the issue persists, please provide a minimum reproducible example. This helps us to investigate the problem more effectively. You can follow the guidelines here: Minimum Reproducible Example.
-
Local Inference: For performing local inference, you can use the following code snippet. Ensure that the
best.pt
file is correctly specified and that thedata.yaml
file is accessible.import torch # Load model model = torch.hub.load('ultralytics/yolov5', 'custom', path='path/to/best.pt') # Perform inference img = 'path/to/your/image.jpg' results = model(img) # Print results results.print() results.save() # Save results to runs/hub
-
Batch Inference: If you need to perform batch inference on a test set, you can use the following approach:
import torch from pathlib import Path # Load model model = torch.hub.load('ultralytics/yolov5', 'custom', path='path/to/best.pt') # Directory containing test images test_dir = Path('path/to/test/images') # Perform inference on all images in the directory for img_path in test_dir.glob('*.jpg'): results = model(img_path) results.save() # Save results to runs/hub
Ultralytics HUB Batch Testing
Currently, Ultralytics HUB supports online inference for individual images. For batch testing, you would need to perform inference locally as described above.
If you continue to face issues, please share the exact steps and code you are using, along with any additional error messages. This will help us provide more targeted assistance.
Thank you for your patience and understanding. The YOLO community and the Ultralytics team are here to support you!
