Keras 需要 TensorFlow 2.2 或更高版本，我有 tensorflow 2.4

Question

这是我的系统信息：

• python == 3.7.9
• keras == 2.2.0
• Tensorflow 2.2.0

我也试过

• keras == 2.4.0
• Tensorflow 2.4.0

我也尝试安装 VC_redist.x64 但它并不总是有效

有什么解决办法吗？

我认为问题出在您的 PATH 环境变量中。 IDE 终端使用的包与您选择的 IDE 环境（和解释器）使用的包不同。 尝试将 PATH 变量中的路径（不要忘记 PATH 系统）更改为 IDE 环境使用的相同路径。 因此，您将使用 IDE 环境的相同版本和相同包（因此 TensorFlow 2.4 而不是 2.2）

如果您从 IDE 终端运行，请不要忘记重新启动 IDE（或创建一个新的 session 终端），以便它加载您的环境变量的新路径。
