Question

我在Windows 8上使用带有Python 3.4 64位的Anaconda

在尝试使用scikit-neuralnetwork包时，这行代码引发了以下异常：

from sknn.mlp import Classifier, Layer

我安装了GCC和g ++（4.8.1）编译器并将它们正确添加到PATH中，但是仍然出现以下错误：

WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to               execute optimized C-implementations (for both CPU and GPU) and will default to   Python implementations. Performance will be severely degraded. To remove this   warning, set Theano flags cxx to an empty string.
Problem occurred during compilation with the command line below:

Answer 1

此错误通常通过运行以下内容来解决，如documentation中所述。

conda install mingw libpython

由于您现在已经安装了自己的GCC安装，因此您可能需要使用环境变量，尤其是PATH以使其工作正常。
