# Run Depth Anything V1 with Keras 3: JAX, PyTorch, or TensorFlow

# zeromodels/depth_anything_base

Paper: [Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data (arXiv:2401.10891)](https://arxiv.org/abs/2401.10891) · [HF Papers](https://huggingface.co/papers/2401.10891)

Depth Anything estimates depth from a single image. A DINOv2 ViT backbone feeds a DPT-style neck and head. V1 outputs relative inverse depth (larger means closer; units are arbitrary within one image).

For more details on the model, please go to the upstream [model card](https://huggingface.co/LiheYoung/depth-anything-base-hf).

Pure-**Keras 3** conversion of [`LiheYoung/depth-anything-base-hf`](https://huggingface.co/LiheYoung/depth-anything-base-hf) for [zeromodels](https://github.com/IMvision12/ZeroModels). One implementation runs unmodified on **TensorFlow / Torch / JAX**.

This is a **monocular depth** checkpoint (`DepthAnythingV1DepthEstimation`) with relative inverse depth.

## ✨ Quick start

```python
import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from PIL import Image
from zeromodels.models.depth_anything_v1 import DepthAnythingV1DepthEstimation, DepthAnythingV1ImageProcessor

model = DepthAnythingV1DepthEstimation.from_weights("zeromodels/depth_anything_base")
processor = DepthAnythingV1ImageProcessor.from_weights("zeromodels/depth_anything_base")

image = Image.open("your_image.jpg").convert("RGB")
output = model(processor(image)["pixel_values"], training=False)
depth = processor.post_process_depth_estimation(
    output, original_size=(image.height, image.width)
)
print(depth.shape)
```

Load any Depth Anything V1 variant the same way with `from_weights("zeromodels/<variant>")`:

| Variant | Hub | Backbone |
|---|---|---|
| `depth_anything_small` | [`zeromodels/depth_anything_small`](https://huggingface.co/zeromodels/depth_anything_small) | ViT-S/14 |
| `depth_anything_base` | [`zeromodels/depth_anything_base`](https://huggingface.co/zeromodels/depth_anything_base) | ViT-B/14 |
| `depth_anything_large` | [`zeromodels/depth_anything_large`](https://huggingface.co/zeromodels/depth_anything_large) | ViT-L/14 |

## Tips

- Set `KERAS_BACKEND` **before** importing Keras / zeromodels.
- For metric (metre) depth, use Depth Anything V2 metric heads.
- See [Depth Anything V1 docs]({DOCS_URL}) and [Loading Weights](https://imvision12.github.io/ZeroModels/loading_weights/).
- Community / upstream weights: `DepthAnythingV1DepthEstimation.from_weights("hf:LiheYoung/depth-anything-base-hf")`.

## Special Thanks

A huge thank you to the Depth Anything authors for creating and releasing these models.
