# Depth Anything Core ML Models

Depth Anything model was introduced in the paper [Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data](https://arxiv.org/abs/2401.10891) by Lihe Yang et al. and first released in [this repository](https://github.com/LiheYoung/Depth-Anything).

Disclaimer: The team releasing Depth Anything did not write a model card for this model so this model card has been written by the Hugging Face team.

## Model description

Depth Anything leverages the [DPT](https://huggingface.co/docs/transformers/model_doc/dpt) architecture with a [DINOv2](https://huggingface.co/docs/transformers/model_doc/dinov2) backbone.

The model is trained on ~62 million images, obtaining state-of-the-art results for both relative and absolute depth estimation.

## Download

Install `huggingface-hub`

```bash
pip install huggingface-hub
```

To download one of the `.mlpackage` folders to the `models` directory:

```bash
huggingface-cli download \
  --local-dir models --local-dir-use-symlinks False \
  coreml-projects/depth-anything \
  --include "DepthAnythingSmallF16.mlpackage/*"
```

To download everything, skip the `--include` argument.
