了解清單檔案摘要

此清單檔案摘要包含以下資訊。

• 驗證期間遇到的 終端清單檔案內容錯誤 錯誤資訊。

• 訓練和測試資料集中 非終端 JSON Line 驗證錯誤 的錯誤位置資訊。

• 錯誤統計資料，例如在訓練和測試資料集中找到的無效 JSON Lines 總數。

如果沒有 終端清單檔案錯誤，即會在訓練期間建立清單檔案摘要。若要取得清單檔案摘要檔案 (manifest_summary.json) 的位置，請參閱 取得驗證結果。

注意

清單檔案摘要中不會回報服務錯誤和清單檔案錯誤。如需詳細資訊，請參閱 終端錯誤。

如需特定清單檔案內容錯誤的資訊，請參閱 終端清單檔案內容錯誤。

清單檔案摘要檔案格式

清單檔案有 2 個區段：statistics 和 errors。

統計資訊

statistics 包含訓練和測試資料集中錯誤的相關資訊。

• training — 在訓練資料集中找到的統計資料和錯誤。

• testing — 在測試資料集中找到的統計資料和錯誤。

errors 陣列中的物件包含清單檔案內容錯誤的錯誤代碼和訊息。

error_line_indices 陣列包含具有錯誤的訓練或測試清單檔案中每個 JSON Line 的行號。如需詳細資訊，請參閱 修正訓練錯誤。

錯誤

跨越訓練和測試資料集的錯誤。例如，當沒有足夠的可用標籤與訓練和測試資料集重疊時，就會發生 ERROR_INSUFFICIENT_USABLE_LABEL_OVERLAP。

清單檔案摘要範例

下列範例是部分清單檔案摘要，會顯示終端清單檔案內容錯誤 (ERROR_TOO_MANY_INVALID_ROWS_IN_MANIFEST)。error_json_line_indices 陣列包含對應的訓練或測試驗證清單檔案中非終端 JSON Line 錯誤的行號。
