Oxford 17 Flowers — ResNet18 (97.8% test accuracy)

ResNet18 fine-tuned on the Oxford 17 Flowers dataset. Classifies RGB images into 17 flower categories.

Successor of the from-scratch educational CNN at darjja/oxford-17-flowers-cnn — same CLI, much higher accuracy:

ModelTest accuracy
From-scratch CNN, 64×64 (original)62.13%
From-scratch CNN + augmentation & label smoothing66.91%
ResNet18 fine-tuned, 224×224 (this repo)97.79%

Quick start

pip install torch torchvision huggingface_hub pillow

Download the script and run it on any image:

huggingface-cli download sergiudanstan/oxford-17-flowers-cnn predict.py --local-dir .
python predict.py your_flower.jpg
python predict.py your_flower.jpg --top 5

The script downloads flower_cnn.pth, config.json, and model.py from this repo automatically on first run.

Training recipe

  • ImageNet-pretrained ResNet18 (torchvision IMAGENET1K_V1), full fine-tune at 224×224
  • Differential learning rates: backbone 1e-4, new head 1e-3 (AdamW, weight decay 1e-4)
  • CosineAnnealingLR, label smoothing 0.1, early stopping on validation accuracy
  • Augmentation: RandomResizedCrop(0.7–1.0), horizontal flip, rotation ±15°, ColorJitter 0.2
  • Split: 924 train / 164 val (15%, seed 42) / 272 official test
  • ~3 minutes on a laptop RTX 5050
