無法在使用張量流的python中定義變量？

Question

我試圖運行簡單的tensorflow的Hello World程序，但它不能在CMD運行，但相同的代碼工作在Python的IDLE我怎麼可以在CMD下運行它是什麼我輸入：

Python有從其他模塊導入的符號的能力，而且也適用，如果這些模塊在同一個文件夾中。一個模塊可以只是一個.py文件，你可以用相同的語法從它導入符號。

現在你的問題是，你的腳本文件名爲tensorflow.py和陰影真正tensorflow模塊，所以任何import語句將不使用真正的tensorflow模塊，而是你自己的腳本。

解決方法是重命名腳本，並且不要使用您使用的模塊的名稱命名腳本。
