在 Windows 上安裝/升級 tensorflow 2

Question

我在以管理員權限打開cmd后運行了下面的命令。 我目前有 tensorflow '1.15.0' ，我的 python 是3.7.3 ，我的 pip 是pip 19.3.1 from c:\\users\\nnn\\anaconda3\\lib\\site-packages\\pip (python 3.7)

1. 我應該升級grpcio嗎？
2. 我需要擔心下面更新 2 中的警告嗎？

錯誤信息是

**ERROR: tensorboard 2.1.0 has requirement grpcio>=1.24.3, but you'll have grpcio 1.24.0 which is incompatible.**

----------------更新 2

我嘗試使用--user選項運行相同的命令並更新了grpcio ，我收到以下消息。 錯誤消息位於底部。 我是否必須激活 conda 環境才能使用 tensorflow 2？ 我不能直接在 Windows 中使用，因為我使用過以前的版本或 tensorflow？
