# Panda — particle panoptic detector

Query-based panoptic detector segmenting individual particle instances with per-particle PID over a PTv3 backbone.

- **pimm type:** `detector-v4` · 32 queries · 6-class PID

## Loading

```python
import pimm
model = pimm.from_pretrained("hf://deeplearnphysics/panda-particle")
```

Architecture + hyper-parameters travel in `config.json`, so no config file is
needed. Weights are bitwise-identical to the original checkpoint.

## Provenance

Repackaged from the original [`panda`](https://github.com/DeepLearnPhysics/panda) checkpoints into the [`pimm`](https://github.com/youngsm/particle-imaging-models) export format. Inherits the source repo's license.
