【问题描述】：

为此苦苦挣扎了 3 天。我已经有 tensorflow 在其他 3 台机器上工作，但需要在未来的高性能 CPU 上安装它。尝试使用 pip 安装 tensorflow 时出现以下 DLL 导入错误。

处理器：Intel(R) Xeon(R) CPU 系统类型：64位基于我已经尝试过的其他解决方案

已按照 Tensorflow 安装页面上的所有说明进行操作

已安装 Microsoft Visual C++ 2015 Redistributable Update
在安装多个 Anaconda 版本后尝试使用 Conda 包
尝试了一些替代的 [whl][1]，因为我在 AVX2 中找不到我的 CPU CPU 列表
尝试了多个单独的版本（Python 3.5、3.6、tensorflow 1.12.0、1.9.0、1.6.0 等）（即没有 anaconda）

pywrap_tensorflow_internal 导入

ImportError：DLL 加载失败，错误代码为 -1073741795

【解决方案1】：

尝试安装 Python 3.6.0 和 Tensorflow 1.5.0。收到“google.protobuf.pyext import _message”错误。所以按照this我升级到3.6.1。我现在可以导入张量流了！所以看起来我必须使用 tensorflow 1.5.0 版本
