成功安装theano后,我使用:

import theano

它只是告诉我警告:

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.

未检测到g ++!但我已经成功安装了g ++:

C:\Users\dell>g++ -v

我想优化我的程序并使用GPU加速,我该如何解决这个问题?非常感谢你!

  • Win7,64操作系统
  • 安装了MinGW
  • Pycharm
  • theano-0.8.2,python2.7

答案 0 :(得分:1)

当我第一次import theano时,我遇到了错误error: '::hypot' has not been declared,我跟着this post成功导入了它。

然后在win10上为我工作了以下步骤

  1. 安装mingw64
  2. C:\Program Files\mingw-w64\mingw64\bin添加到路径
  3. 重新启动计算机
  4. 然后警告消失了
