YOLOv5 release v6.2 brings support for classification model training, validation, prediction and export! We've made training classifier models super simple. Click below to get started.
Classification Checkpoints (click to expand)
We trained YOLOv5-cls classification models on ImageNet for 90 epochs using a 4xA100 instance, and we trained ResNet and EfficientNet models alongside with the same default training settings to compare. We exported all models to ONNX FP32 for CPU speed tests and to TensorRT FP16 for GPU speed tests. We ran all speed tests on Google Colab Pro for easy reproducibility.
