YOLOv5

You'll Easily Log Everything if you combine W&B with YOLOv5.

Ultralytics' YOLOv5 ("You Only Look Once") model family enables real-time object detection with convolutional neural networks without all the agonizing pain.

Weights & Biases is directly integrated into YOLOv5, providing experiment metric tracking, model and dataset versioning, rich model prediction visualization, and more. It's as easy as running a single pip install before you run your YOLO experiments!

For a quick overview of the model and data-logging features of our YOLOv5 integration, check out this Colab and accompanying video tutorial, linked below.

All W&B logging features are compatible with data-parallel multi-GPU training, e.g. with PyTorch DDP.

Core Experiment Tracking

Simply by installing wandb, you'll activate the built-in W&B logging features: system metrics, model metrics, and media logged to interactive Dashboards.

pip install wandb
git clone https://github.com/ultralytics/yolov5.git
python yolov5/train.py # train a small network on a small dataset

Just follow the links printed to the standard out by wandb.

All these charts and more!

Model Versioning and Data Visualization

But that's not all! By passing a few simple command line arguments to YOLO, you can take advantage of even more W&B features.

  • Passing a number to --save_period will turn on model versioning. At the end of every save_period epochs, the model weights will be saved to W&B. The best-performing model on the validation set will be tagged automatically.

  • Turning on the --upload_dataset flag will also upload the dataset for data versioning.

  • Passing a number to --bbox_interval will turn on data visualization. At the end of every bbox_interval epochs, the outputs of the model on the validation set will be uploaded to W&B.

python yolov5/train.py --epochs 20 --save_period 1

python yolov5/train.py --epochs 20 --save_period 1 \
--upload_dataset --bbox_interval 1

Every W&B account comes with 100 GB of free storage for datasets and models.

Here's what that looks like.

Model Versioning: the latest and the best versions of the model are identified.
Data Visualization: compare the input image to the model's outputs and example-wise metrics.

With data and model versioning, you can resume paused or crashed experiments from any device, no setup necessary! Check out the Colab for details.
