# Checkpoints Layout

All inference checkpoints should be placed under `checkpoints/`.

```text

      g_00125000.pt                  # required for stage1

      sovits5.0_all_nocross/*.pt     # default non-cross inference

    vits_pretrain/
      sovits5.0.pretrain.pth         
```

Notes:

1. If your cross checkpoint directory is `sovits5.0_all_cross/`, pass it explicitly with `--model` (`stage2`) or `--stage2-model` (`pipeline`).
2. `speaker_pretrain/best_model.pth.tar` is used by `build-spk`; it is not required when you already have ready-made `.spk.npy` files.
