# SimpleEval per-prompt viewer

Step through the same prompt's images across the runs in
`test/simpleeval_sampled_inference/` (one column per run, e.g. `ep10·cfg9`,
`ep20·cfg7`), one prompt at a time.

## Run it

```bash
cd /scratch3/len091/nanogen_repos/nanogen_inf
python test/simpleeval_sampled_inference/viewer/gen_manifest.py --serve
```

It prints the URL, e.g.:

```
http://virga-login:8000/test/simpleeval_sampled_inference/viewer/index.html
```

Remote machine? Forward the port first, then open the `localhost` URL:

```bash
ssh -L 8000:localhost:8000 virga-login
```

Use `--port N` for a different port.

## Controls

- `←` / `→`, **Prev** / **Next**, or the slider — step through prompts
- **Random** (or press `r`) — jump to a random prompt
- prompt **#** box — jump to a specific index
- **size** slider — scale the images; click an image to open it full-res

## Scores

Each run's `vqascore_qwen3-vl-8b.npy` (one score per image, 0–1) is shown under
the image, colored red→green by value, with the run's mean score in the column
header. Runs without that `.npy` show `—`.

## Notes

- Under `--serve`, the manifest is rebuilt live on each page load, so adding more
  run folders (other epochs/cfgs) into `simpleeval_sampled_inference/` just shows
  up as new columns on refresh. A `not generated` placeholder appears for any run
  missing a given prompt index.
- Without `--serve` you can instead serve the repo root with `python -m http.server`
  and open the same path; it then reads the static `manifest.json` snapshot that
  `gen_manifest.py` also writes (re-run the script to refresh it).
