笔者小白在开始训练神经网络的期间遇到以下的报错信息:

Using Theano backend.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.

解决方法如下

在anaconda Prompt里面执行如下的安装命令:

conda install mingw libpython
