Status — documented recipe (placeholder). A production-grade pipeline from Ropedia Academy for an advanced, GPU-heavy task. Everything below — base model, objective, dataset, config, the exact evaluation — is specified; the weights / metrics / figures land here automatically when you run the notebook on a GPU (one click below). Try the trained models live in the Ropedia demos Space.

At a glance


Base model	facebook/sam2-hiera-large (pretrained)
Task	promptable video object segmentation
Training objective	Promptable mask prediction + memory propagation across frames (inference).
Track	C · Egocentric vision
Built on	facebookresearch/sam2
Notebook	Open In Colab
Compute / storage / time	GPU required — see the Compute · storage · time table in the notebook

Dataset

Source: Your video + click/box prompts. Benchmark: DAVIS 2017 / SA-V.

Training config

GPU-scale — the notebook ships a demo profile (free Colab T4) and a full profile, with an exact Compute · storage · time table. Hyperparameters (optimizer, steps, batch, LoRA rank, …) are in the training cell.

Evaluation results

⏳ Pending — run the notebook on a GPU to fill this in. This lab reports J&F mean (region IoU + boundary F) on a held-out split (see its Evaluate cell).

Inference example

No weights are published yet. After a GPU run, load the checkpoint/adapter the notebook saves (it also has a ready inference cell). Base model: facebook/sam2-hiera-large (pretrained).

How to fill this repo

Open the notebook in Colab → Runtime → GPU → Run all (runs the real pipeline).
Run its Publish to the Hugging Face Hub step (or HfApi().upload_folder(...)) — the checkpoint + metrics.json + figures replace this placeholder.

Train / run on a GPU · [ ] upload weights · [ ] add metrics.json · [ ] add figures · [ ] swap in the real results card

Limitations

Not yet trained — no numbers to report. The pipeline is GPU-heavy (see the compute table); on free Colab use the demo-scale settings. This is an educational, reproducible recipe, not a tuned production release.
