## Change History
|
||||
|
||||
- 27 Mar. 2023, 2023/3/27:
|
||||
- Fix issues when `--persistent_data_loader_workers` is specified.
|
||||
- The batch members of the bucket are not shuffled.
|
||||
- `--caption_dropout_every_n_epochs` does not work.
|
||||
- These issues occurred because the epoch transition was not recognized correctly. Thanks to u-haru for reporting the issue.
|
||||
- Fix an issue that images are loaded twice in Windows environment.
|
||||
- Add Min-SNR Weighting strategy. Details are in [#308](https://github.com/kohya-ss/sd-scripts/pull/308). Thank you to AI-Casanova for this great work!
|
||||
- Add `--min_snr_gamma` option to training scripts, 5 is recommended by paper.
|
||||
|
||||
- Add tag warmup. Details are in [#322](https://github.com/kohya-ss/sd-scripts/pull/322). Thanks to u-haru!
|
||||
- Add `token_warmup_min` and `token_warmup_step` to dataset settings.
|
||||
- Gradually increase the number of tokens from `token_warmup_min` to `token_warmup_step`.
|
||||
- For example, if `token_warmup_min` is `3` and `token_warmup_step` is `10`, the first step will use the first 3 tokens, and the 10th step will use all tokens.
|
||||
- Fix a bug in `resize_lora.py`. Thanks to mgz-dev! [#328](https://github.com/kohya-ss/sd-scripts/pull/328)
|
||||
- Add `--debug_dataset` option to step to the next step with `S` key and to the next epoch with `E` key.
|
||||
- Fix other bugs.
|
||||
|
||||
- `--persistent_data_loader_workers` を指定した時の各種不具合を修正しました。
|
||||
- `--caption_dropout_every_n_epochs` が効かない。
|
||||
- バケットのバッチメンバーがシャッフルされない。
|
||||
- エポックの遷移が正しく認識されないために発生していました。ご指摘いただいたu-haru氏に感謝します。
|
||||
- Windows環境で画像が二重に読み込まれる不具合を修正しました。
|
||||
- Min-SNR Weighting strategyを追加しました。 詳細は [#308](https://github.com/kohya-ss/sd-scripts/pull/308) をご参照ください。AI-Casanova氏の素晴らしい貢献に感謝します。
|
||||
- `--min_snr_gamma` オプションを学習スクリプトに追加しました。論文では5が推奨されています。
|
||||
- タグのウォームアップを追加しました。詳細は [#322](https://github.com/kohya-ss/sd-scripts/pull/322) をご参照ください。u-haru氏に感謝します。
|
||||
- データセット設定に `token_warmup_min` と `token_warmup_step` を追加しました。
|
||||
- `token_warmup_min` で指定した数のトークン（カンマ区切りの文字列）から、`token_warmup_step` で指定したステップまで、段階的にトークンを増やしていきます。
|
||||
- たとえば `token_warmup_min`に `3` を、`token_warmup_step` に `10` を指定すると、最初のステップでは最初から3個のトークンが使われ、10ステップ目では全てのトークンが使われます。
|
||||
- `resize_lora.py` の不具合を修正しました。mgz-dev氏に感謝します。[#328](https://github.com/kohya-ss/sd-scripts/pull/328)
|
||||
- `--debug_dataset` オプションで、`S`キーで次のステップへ、`E`キーで次のエポックへ進めるようにしました。
|
||||
- その他の不具合を修正しました。
|
||||
|
||||
|
||||
- 21 Mar. 2023, 2023/3/21:
|
||||
- Add `--vae_batch_size` for faster latents caching to each training script. This batches VAE calls.
|
||||
- Please start with`2` or `4` depending on the size of VRAM.

|
||||
- Windows以外の環境向けに、画像ファイルの大文字の拡張子をサポートしました。
|
||||
- `resize_lora.py` を dynamic rank （rankが各LoRAモジュールで異なる場合、`conv_dim` が `network_dim` と異なる場合も含む）の時に正しく動作しない不具合を修正しました。toshiaki氏に感謝します。
