Question

我想在Windows 10 64位和vanilla Python 3.5安装上使用Theano。这就是我陷入困境的地方：

我从python.org获得了Python 3.5.2 64位版本。
我从Christoph Gohlke的页面安装了NumPy 1.11.2和SciPy 0.18.1。
pip install theano给了我Theano 0.8.2
我安装了MSYS2，然后使用Pacman安装MinGW64。
我将MinGW添加到PATH。
D：\ Python35 \ Libs中有一个libpython35.a，虽然我没有把它放在那里。

现在我在尝试运行Theano测试或Lasagne时遇到了这些错误：

我做错了什么？

Answer 1

Theano文档声明他们不喜欢包含空格的路径。但他们从未意识到包含重音字母的路径也会使代码崩溃。我的Windows用户名来自我的Microsoft帐户，该帐户使用我的全名，其中包含á，我是匈牙利人。将此添加到.theanorc可解决问题。

[global]
base_compiledir = D:\theano\
