| # LibreZipDepthbnpu-depth |
|
|
| ZipDepth base with the NPU decoder: a ~6M-parameter reparameterizable CNN |
| (RepVGG encoder, SPPF + cross-scale neck, FPN decoder) for zero-shot relative |
| monocular depth estimation, repackaged for LibreYOLO. This checkpoint carries |
| a separately trained unfold-free convex-upsampling head for NPU/edge compilers |
| that lack gather/unfold support; use it when exporting to constrained runtimes. |
| The standard GPU/CPU checkpoint is |
| [LibreZipDepthb-depth](https://huggingface.co/LibreYOLO/LibreZipDepthb-depth). |
|
|
| ## Usage |
|
|
| ```python |
| from libreyolo import LibreYOLO |
| |
| model = LibreYOLO("LibreZipDepthbnpu-depth.pt") # auto-downloads from this repo |
| results = model.predict("image.jpg", save=True) |
| depth = results[0].depth_map.data # (H, W) relative inverse depth |
| model.export(format="onnx") # unfold-free fixed-resolution graph |
| ``` |
|
|
| Outputs follow LibreYOLO's depth task contract: a dense float map on the |
| original image canvas, higher values mean closer to the camera, no metric unit. |

| ## Modifications |
|
|
| LibreYOLO checkpoint-schema metadata wrap only. Learned parameters are |
| byte-identical to upstream. See `weights/convert_zipdepth_weights.py` in the |
| [LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo). |
|
|
| ## Training-data provenance |
|
|
| Upstream trained these weights by distilling pseudo-labels produced by Depth |
| Anything V2 Large (a CC-BY-NC-4.0 checkpoint) over ~14M images from 17 public |
| datasets. The MIT grant on the resulting student weights is the upstream |
| authors' published licensing position; the lineage is documented here for |
| transparency. |
