關於 Train Flux LoRA
從影像的 zip 封存檔(`images_data_url`)微調 LoRA,其中可包含相應的描述文字檔。使用 `trigger_word` 命名概念,並以 `is_style` 啟用樣式訓練,此設定會關閉分割與描述功能。`create_masks` 會將損失權重偏向主體,`steps` 接受 1 到 10000。會回傳 diffusers LoRA 權重與設定檔。
參數
名稱類型
預設值允許值
說明
images_data_url必填
類型string
透過 ZIP 封存檔 URL 提供圖像,也可選擇讓每張圖像搭配同名的說明文字檔。建議至少 4 張圖像;通常圖像集越大越好。
trigger_word選填
類型string | null
說明缺少時,提供觸發詞作為說明替代文字;現有說明會阻止 trigger_word 使用。設為 None 可不使用觸發詞。
create_masks選填
類型boolean
預設值true
設為 True 可啟用以遮罩加權訓練損失;對人物圖像而言,會盡可能使用臉部遮罩。
steps選填
類型integer | null
1 – 10,000
LoRA 的訓練步數。
is_style選填
類型boolean
預設值false
設為 True 可啟用風格訓練,並透過觸發詞指定風格。在此模式中,觸發詞會取代說明文字,且停用分割。
is_input_format_already_preprocessed選填
類型boolean
預設值false
提供資料的預處理狀態:True 表示資料集已完成預處理。預設值 False 則需要基礎名稱相符的原始圖像/說明配對,例如 'photo.jpg' 和 'photo.txt'。
data_archive_format選填
類型string | null
封存格式;省略時會從其 URL 推斷。
