安裝 Tensorflow 和 pip 時出現問題

Question

我正在嘗試通過在 powershell 中使用 pip 來安裝 tensorflow。 我在 windows 10 上並且沒有使用虛擬環境。 （我對格式的要求，我不得不手動添加換行符。）

這是來自 powershell 的 output，因為我檢查了 pip 和 Z23EEEB4347BDD7526BFC6B7EEDA 的哪些版本：

PS C:\Users\User> py --version  
Python 3.7.8  
PS C:\Users\User> pip3 --version  
pip 21.3.1 from C:\Users\User\AppData\Roaming\Python\Python37\site-packages\pip (python 3.7)  

最后，這里是 output，因為我嘗試使用 pip 安裝 tensorflow

PS C:\Users\User> pip3 install --upgrade tensorflow  
Defaulting to user installation because normal site-packages is not writeable

Answer 1

嘗試將套接字超時設置為更高的值：

pip3 install -U --upgrade --timeout 10000 tensorflow

Answer 2

嘗試安裝 pandas 時遇到同樣的問題

python -m pip install pandas

使用時

pip3 install -U --upgrade --timeout 10000 pandas

它有效，謝謝
