Tensorflow Saver.Save（），FailedPreconditionError，重命名失敗：...進程無法訪問文件，因爲它正在被另一個進程使用

Question

試圖使用Saver保存會話。而遇到了一個錯誤：

FailedPreconditionError (see above for traceback): Failed to rename: ./Language_model_lab3-0.data-00000-of-00001.tempstate15754770084434331914 to: ./Language_model_lab3-0.data-00000-of-00001 : The process cannot access the file because it is being used by another process.

下面是代碼：

saver.save(session, "./Language_model_lab3", global_step=i) 

這裏是報告全文：

saver.save(session, "./Language_model_lab3", global_step=i)

Answer 1

我搜索這個網站，唯一的答案與Dropbox相關，我沒有運行Dropbox。由語義反病毒，Mircosoft Onedrive和谷歌備份/同步。沒有幫助。

我試圖使用「進程探索」來搜索哪個進程已鎖定文件/文件夾，找不到任何。

所以我在「immediated窗口」嘗試這樣做：（一招，所以我可以測試而無需重新啓動該程序的東西）

和它的工作。

saver.save(session, "./Language_model_lab3/", global_step=i) 
'./Language_model_lab3/-0' 

如果我添加一個文件名：

saver.save(session, "./Language_model_lab3/Model.ckpt", global_step=i) 
'./Language_model_lab3/Model.ckpt-0' 

所以我解決它通過使用特定的子文件夾我的代碼。不知道爲什麼。 :)

我張貼在這裏，因爲我無法在網上找到類似的解決方案。
