在 Windows 10 (Python 3.8.3) 上安装 TensorFlow 时出错

Question

在 Windows 10 和 Python 3.8.3 上。 我安装了 TensorFlow 使用

pip install tensorflow==2.0.0 

但得到以下错误。 关于如何解决这个问题的任何建议？

Failed to load the native TensorFlow runtime.

Answer 1

Python 3.8 支持从 TensorFlow 2.2 或更高版本开始。 因此，您面临上述问题。

您可以使用pip install tensorflow 。 TensorFlow 2 个包需要pip version > 19.0 。

您需要从此处下载并安装/更新 Microsoft Visual C++ 2015-2019 Redistributable (x64)。

如果您仍然面临 DLL 加载失败错误，可能的原因是

• 你的 CPU/Python 是 32 位的（应该是 64 位的）
• 有一个库位于不同的位置/未安装在您的系统上，无法加载。
