合併之後, 更改train.record和test.record, 進行training. 會出現以下錯誤碼:error message: InvalidArgumentError: Invalid JPEG data or crop window查閱google後(下述連結), https://blog.csdn.net/qq_36190978/article/details/95937723?depth_1-utm_source=distribute.pc_relevant.none-task&utm_source=distribute.pc_relevant.none-task發現可能有些JPEG格式是progressive, 而不是baseline. 修改完,這些JPEG後, 檢查全部都是baseline後, 重train, 仍然出現相同error message: InvalidArgumentError: Invalid JPEG data or crop window請問該如何解決????

2020/03/17: 發現JPEG改正後, 沒有重新產生train.record和test.record所導致. 但是run下去後, 發現下面的error code. 請問該如何解決??????

=== error code====

有幾個可能:

在做DATA處理的時候, JPEG 有ERROR 也許是 bit loss.

建議是從頭執行:

1. 原始的資料集先行利用 open CV 確認所有 JPEG 都是 baseline

2. DATA augument 後, 確認 IMAGE data size 符合

3. 資料集分成 train/test

4. 進行訓練
