Question

很抱歉，如果碰巧这件事情变得微不足道，因为我碰巧是这些东西的新手。我设置theano使用我的gpu在ubuntu trusty 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
Traceback (most recent call last):
  File "test.py", line 11, in <module>
    f = function([], T.exp(x))

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提供的脚本：http://deeplearning.net/software/theano/tutorial/using_gpu.html 配置有问题吗？我相信所有依赖项都设置正确，但我可能犯了一些错误，但之后我可能会遇到运行时错误之外的问题。我在github上搜索了很多与此相关的信息，但一无所获。搜索stackoverflow之后的结果相同，heance我在这里发布。任何帮助表示赞赏。谢谢

附加信息：python3.4，theano流血边版。 Libgpuarray，clblas，openblas都是从git source master分支构建的。 64位架构。

Answer 1

Theano对OpenCL的支持还没有准备好，开发团队似乎并没有优先考虑这项工作（参见this issue）。所以要么你需要一些耐心，要么你需要一个可以运行CUDA的nvidia GPU。

Python，theano Runtimeerror：无法初始化elemwise支持
