【问题描述】：

我使用命令安装了 tensorflow 1.8.0

pip3 install --upgrade tensorflow

它安装正确，但是当我输入命令时

`import tensorflow as tf`

出现以下错误：

Failed to load the native TensorFlow runtime.

我搜索了很多。我什至再次安装了 tensorflow，但徒劳无功。我在互联网上找不到任何解决方案。有人能帮我吗？先感谢您。 :)

【解决方案1】：

TensorFlow Windows 软件包仅适用于 64 位 Python。您的 Python 安装似乎是 32 位的。安装 64 位 Python 版本，您应该可以毫无问题地安装 TensorFlow。

【解决方案2】：

我在我的 Windows 7 64 位中遇到了完全相同的问题。就我而言，Python 3.7.6 的 TensorFlow 2.1 已安装好。当我运行一个小演示时会出现此错误。所以我安装了Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019，X64 版本，一切都很有魅力。
