加載預訓練的權限錯誤 Model、Django、AWS

Question

我正在努力在 AWS 上部署 Django 應用程序。 在本地，一切正常。 部署后，網站打開正常，但當我嘗試運行深度學習 model 時，它給了我一個 Errno 13 權限錯誤。 /severity 是發生這種情況的網站頁面。 任何和所有幫助表示贊賞:)

我文件中導致此問題的代碼是：

Answer 1

看來您的手電筒 package 正在嘗試創建一個目錄，但它沒有寫入權限，因此出現權限被拒絕錯誤。 我不能確切地告訴它試圖創建目錄的位置（它似乎在根目錄中，即 /home/wsgi）。

我建議，如果您有權訪問此os.makedirs(model_dir) ，請創建一個tmp目錄，將其權限更改為 777（ chmod -R 777 tmp ）並將您的model_dir指向 tmp 目錄（即path_to_temp/tmp/home/wsgi ）

或者您可以在 root 中創建一個目錄並更改其權限。（我不確定，但我認為它可以解決問題）

$ mkdir /home
$ chmod -R 777 /home
