未检测到theano g++
问题描述
我安装了 theano，但是当我尝试使用它时，我得到了这个错误:
I installed theano but when I try to use it I got this error:
警告(theano.configdefaults):未检测到 g++！Theano 将无法执行优化的 C 实现(针对 CPU 和 GPU)，默认为 Python实施.性能会严重下降.
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.
我安装了g++，并且把正确的路径放在环境变量中，所以就像theano没有检测到一样.
I installed g++, and put the correct path in the environment variables, so it is like theano does not detect it.
有谁知道如何解决这个问题或可能是什么原因?
Does anyone know how to solve the problem or which may be the cause?
解决方案
我在更新 XCode(通过 App Store)后在 OS X 上发生了这种情况.更新前一切正常，但更新后我必须启动 XCode 并接受许可协议.然后一切又恢复了.
I had this occur on OS X after I updated XCode (through the App Store). Everything worked before the update, but after the update I had to start XCode and accept the license agreement. Then everything worked again.
