使用SYCL支持安装Tensorflow

Question

我想使用gdb跟踪Eens SYCL支持的Tensorflow操作内核实现。 但是，当我尝试安装.whl包时，会弹出一些关于fglrx的错误消息。

错误消息

Compiling /tmp/pip-1vfYDJ-build/tensorflow-1.0.1.data/purelib/tensorflow/contrib/cudnn_rnn/ops/gen_cudnn_rnn_ops.py ...
  File "/tmp/pip-1vfYDJ-build/tensorflow-1.0.1.data/purelib/tensorflow/contrib/cudnn_rnn/ops/gen_cudnn_rnn_ops.py", line 1
    Error: Fail to load fglrx kernel module!
             ^
SyntaxError: invalid syntax ....

配置

• CPU：Intel Core i7-4790
• GPU：GeForce GT 630 / PCIe / SSE2
• OS：ubuntu 15.04
• 司机：Nvidia binary driver nvidia-352

命令

以下是我根据教程使用的命令。

• bazel build：

  

bazel build -c dbg --config = sycl       // tensorflow /工具/ pip_package：build_pip_package

• build pip package：

  

巴泽勒滨/ tensorflow /工具/ pip_package / build_pip_package

• 安装pip包

  

sudo pip install：   /tmp/tensorflow_pkg/tensorflow-1.0.1-cp27-none-linux_x86_64.whl

请帮我解决问题。

Answer 1

SYCL变体目前需要一个支持SPIR或SPIRV的平台，如Intel或AMD。 NVIDIA平台目前不支持。

Answer 2

您不能（目前）在英特尔GPU上使用带有TensorFlow的SYCL。但是，它即将到来。您需要一些修复，然后它才能正常工作。您将需要等待新的Intel OpenCL GPU驱动程序，然后在TensorFlow上进行一些兼容性提交，然后才能在Intel GPU上运行。您可能还需要等待一段时间才能获得一些性能改进，因为我们一直更注重正确性，首先，性能会稍晚一些。
