ubuntu - 在 Ubuntu 18.04 上构建具有 OpenCL 支持的 TensorFlow 失败

Question

在尝试使用此 configuration 在 Ubuntu 18.04 上编译 Tensorflow 时我遇到了这个错误:

如果有人可以帮助我，我将不胜感激，我已经尝试解决这个问题一段时间了，但似乎没有任何效果。我也尝试过用 triSYCL 编译它，但问题仍然存在，我还确认在没有 OpenCL 支持的情况下编译可以按预期工作，没有任何错误。

最近 SYCL 规范中的接口(interface)发生了变化，因此您需要确保您的 TensorFlow 源代码与 ComputeCpp 版本匹配。

跟随指南here并确保您已下载最新版本的 ComputeCpp 并从 GitHub 获得最新版本的源代码。请注意，您需要使用 Codeplay 分支 here因为更改需要一些时间才能传播到主 TensorFlow 存储库，所以指南中对此进行了概述。
