【问题描述】:
对不起,如果这碰巧是微不足道的,因为我碰巧对这些东西不熟悉。我设置 theano 以使用我的 gpu 在 ubuntu 可信赖的 tahr 上进行计算。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,我收到以下错误:
Mapped name None to device opencl0:0: Turks

RuntimeError: ('The following error happened while compiling the node', GpuElemwise{exp,no_inplace}(<GpuArrayType<None>(float64, (False,))>), '\n', 'Could not initialize elemwise support')
我运行的脚本是网站上可用的脚本:http://deeplearning.net/software/theano/tutorial/using_gpu.html 是不是配置有问题?我相信所有依赖项都已正确设置,但我可能会犯一些错误,但我可能会遇到运行时错误以外的其他错误。我在 github 上搜索了很多与此相关的信息,但一无所获。在stackoverflow上搜索后的结果也是如此,我在这里发布了这个。任何帮助表示赞赏。 谢谢
附加信息:python3.4,theano 前沿版本。 Libgpuarray、clblas、openblas 都是从 git 源码 master 分支构建的。 64 位架构。
