python tensorflow Windows異常

Question

非常感謝您閱讀本文。 我嘗試搜索，但找不到答案。 我一直在嘗試使用python 3.5.2在Windows 8.1上使用pip安裝tensorflow。 我得到這個錯誤。

C:\Users\Default.HP>pip3 install --upgrade tensorflow

嘗試升級點子時，出現此錯誤

C:\Users\Default.HP>python -m pip install --upgrade pip

如何解決呢？

非常感謝。

Answer 1

當pip （以非管理員用戶身份運行）嘗試升級由管理員用戶安裝的軟件包時，會出現此權限錯誤。 有兩種主要解決方法：

1. 使用管理員命令提示符運行升級命令。
2. 將TensorFlow安裝到非管理員用戶擁有的virtualenv中 。

Answer 2

對我來說，問題出在我的互聯網連接上。 發生了許多幻燈片中斷，這些中斷會停止該過程並引發那些異常。

綜上所述，以管理員身份運行終端，並確保下載過程中沒有網絡中斷。
