当我尝试像这样使用 pip 安装 tensorflow 时

pip install tensorflow

它给了我以下错误：

错误是什么意思，我该如何安装？

如果我在谷歌上搜索如何安装 tensorflow，它会告诉我从虚拟环境中下载它，我不知道如何创建虚拟环境

【问题讨论】：

这听起来像是您的互联网连接问题，只需重复该命令直到成功。
Python 3.8 尚未完全支持某些操作系统上的最新 tensorflow（或某些特殊规范）。加载最新的 TensorFlow 可能会出现问题。使用 conda 创建虚拟环境。如果您已经有 Anaconda，只需打开 Anaconda 提示符并输入 conda create -n tf python=3.7 然后输入 conda activate tf。之后，pip install tensorflow
@RaghavGupta 所以我需要安装 python 3.7？
如果你有Anaconda，你不需要下载python 3.7来创建虚拟环境。虚拟环境的目的是让我们不显式安装某些 python 版本。它会为你做的，不用担心。只要确保你通过 anaconda 提示符运行你的命令

【解决方案1】：

正如@Dr. 评论的那样。史努比，错误看起来像连接问题。 TensorFlow 2.2 或更高版本需要 Python 3.8。更多请访问官网Tensorflow。

正如@Raghav Gupta 所建议的，conda 负责处理包版本不兼容问题。

conda create --name tf python=3.8 tensorflow #install python 3.8 and latest version of Tensorflow
