什么导致 TensorFlow 导入错误：DLL 加载失败？

Question

我在 Windows 10 上使用 Anaconda 环境。我已经使用 pip 安装了 tensorflow-gpu，当我尝试导入 tensorflow 时，出现以下导入错误。我尝试使用 cpu 版本的 tensorflow 并使用新的 conda 环境重新安装所有软件包。我的python是3.7版和tensorflow-gpu 2.1.0版。

    >>> import tensorflow as tf
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

您知道导致此错误的原因吗？

Answer 1

• 尝试降级并安装 tensorflow。

pip install tensorflow==2.0

• 如果你使用 gpu

pip install --upgrade tensorflow-gpu==2.0

• 或尝试下载这些 Visual Studio 文件 click here

Answer 2

这可能是因为您的 CPU（可能是旧的）不支持 AVX 指令（例如，Intel Pentium 或类似的）。您可以使用以下方法解决此问题：

pip3 uninstall tensorflow

去这里：link with tensorflow 2.1.0 wheels which has been precompiled with SSE2 instructions。

下载wheel到你的项目，然后使用pip install <filename.wheel>安装tensorflow。 再试一次 - 错误应该得到解决
