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 软件包时，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!

您不能（当前）在英特尔GPU上使用带有TensorFlow的SYCL . 但是，它即将推出 . 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，因为我们一直在更多地关注正确性，首先，性能会稍晚一些 .
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 .
