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 ๐
We're excited to announce the launch of our latest state-of-the-art (SOTA) object detection model for 2023 - YOLOv8 ๐!
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.
Hello! Thanks for providing detailed information about the issue you're encountering. It seems like the error arises because the bounding box coordinates are not correctly normalized to the range (0, 1] after resizing and scaling transformations.
From your code snippet, it appears that you are normalizing the bounding box coordinates by dividing by target_size
after scaling them. However, the error suggests that some values might still be out of the expected range. This could potentially be due to floating-point precision issues or initial values slightly outside the expected range before scaling.
To address this, you might want to ensure that the bounding box coordinates are strictly within the (0, 1] range before they are passed to the augmentation pipeline. Here's a modified version of your label updating loop that includes an additional check and correction for bounding box coordinates:
updated_labels = []
for label in labels4:
class_id, x1, y1, x2, y2 = label
# Scale bounding box coordinates
new_x1 = x1 * scale_x
new_y1 = y1 * scale_y
new_x2 = x2 * scale_x
new_y2 = y2 * scale_y
# Normalize to [0, 1]
new_x1 /= target_size
new_y1 /= target_size
new_x2 /= target_size
new_y2 /= target_size
# Ensure coordinates are within (0, 1]
new_x1 = max(1e-5, min(new_x1, 1))
new_y1 = max(1e-5, min(new_y1, 1))
new_x2 = max(1e-5, min(new_x2, 1))
new_y2 = max(1e-5, min(new_y2, 1))
updated_labels.append([class_id, new_x1, new_y1, new_x2, new_y2])
Please make sure that the initial bounding box coordinates (x1, y1, x2, y2) are within the valid range before transformation. If the issue persists, you might want to add debug prints to check the values of coordinates at each step.
Let me know if this helps or if you have any more questions!
