【问题描述】：

我在带有 Python 3.8（我也安装了 Python 3.9 和 3.6）的 Windows 10 上使用 TensorFlow 2.4，在 ml2u 的虚拟环境中，pip install tensorflow 到目前为止只安装了 TensorFlow 2.4。通过尝试在笔记本中导入 TensorFlow，我收到以下错误消息。按照其他帖子中的建议，我安装了 Microsoft Visual C++ Redistributable，从而安装了 MS Visual 和 VC_redist.x64.exe。

import tensorflow as tf

【解决方案1】：

您可能会遇到此问题，因为您运行的是 32 位 python 或 32 位操作系统。并检查您的 CPU 是否支持 AVX 指令。

请查看system requirements 并检查您是否安装了正确的依赖项。
