# EfficientNet-B6

> Tan & Le, 2019 — *EfficientNet: Rethinking Model Scaling for Convolutional Neural Networks* (arXiv:1905.11946)

[Lucid](https://github.com/ChanLumerico/lucid) port of `torchvision/EfficientNet_B6_Weights.IMAGENET1K_V1`,
converted to Lucid-native safetensors.

## Available weights

| Tag | acc@1 | acc@5 | Params | GFLOPs | Size | Source |
|---|---|---|---|---|---|---|
| `IMAGENET1K_V1` *(default)* | 84.008 | 96.916 | 43.0M | 19.068 | 165.14 MB | torchvision |

## Usage

```python
import lucid.models as models
from lucid.models.weights import EfficientNetB6Weights

# default tag
model = models.efficientnet_b6_cls(pretrained=True)

# explicit tag (enum or string)
model = models.efficientnet_b6_cls(weights=EfficientNetB6Weights.IMAGENET1K_V1)
model = models.efficientnet_b6_cls(pretrained="IMAGENET1K_V1")

# preprocessing travels with the weights
weights = EfficientNetB6Weights.IMAGENET1K_V1
preprocess = weights.transforms()
logits = model(preprocess(image)[None]).logits
```

## Conversion

Converted from `torchvision/EfficientNet_B6_Weights.IMAGENET1K_V1` via
`python -m tools.convert_weights efficientnet_b6 --tag IMAGENET1K_V1`.
Key mapping + numerical parity verified against the source.

## License

`apache-2.0` — inherited from the original weights.
