运行 theano.test() 时出错 - ImportError：DLL 加载失败：动态链接库 (DLL) 初始化例程失败

Question

我正在尝试在 Windows 10 (x64) 机器上启动并运行 theano。

我已经从 WinPython 发行版中安装了 Python，该发行版与 theano 一起运行。但是安装了CUDA 8.0.44和MingW后，运行简单脚本时不断报以下错误

import theano
theano.test()

请注意，我之前有几个警告，我已经解决了（例如，通过从here 安装丢失的包。但是这个错误没有给我任何可用的信息。真正奇怪的是，模块名称没有在任何地方给出那个 theano 不见了。

任何想法如何解决这个问题或找出缺少什么 dll？

解决了这个问题，按照this excellent tutorial（唯一一个实际工作并且是最新的）在 Windows 机器上本地安装深度学习库。
