如果这个问题太简单了，那是因为我对这些东西还很陌生。我在Ubuntu Trusty Tahr上设置theano使用我的GPU进行计算。我有AMD Radeon HD 7670M GPU。当我尝试运行测试脚本以检查theano与GPU的功能时，我遇到以下错误：

我运行的脚本是网站上提供的：http://deeplearning.net/software/theano/tutorial/using_gpu.html是否配置有误？我相信所有依赖项都设置正确，但我可能犯了一些错误，但我可能会遇到其他问题而不是运行时错误。我在github上搜索了很多与此相关的信息，但没有找到任何信息。在stackoverflow上搜索后也得到了同样的结果，因此我在这里发布了这个帖子。感谢任何帮助。 附加信息：python3.4，theano bleeding edge版本。Libgpuarray、clblas、openblas都是从git源主分支构建的。64位架构。
