Impossible de configurer TensorFlow avec OpenCL à l'aide de SYCL

Question

J'ai configuré TensorFlow avec SYCL sur Ubuntu 16.04/AMD RX480 en suivant https://www.codeplay.com/portal/03-30-17-setting-up-tensorflow-with-opencl-using-sycl et j'ai ignoré l'installation des en-têtes AMD OpenCL en raison du conflit de version fglrx.

Puis, a échoué lorsque:

1. Soit fonctionnement: test de Bazel $ --config = sycl -k --test_timeout 1600 - // tensorflow/... - // tensorflow/contrib /. .. - // tensorflow/java/... - // tensorflow/compilateur/...

retourné: /home/ai/.cache/bazel/_bazel_ai/03759b09788dc48db1c2f1f857f3711b/execroot/tensorflow-opencl /bazel-out/local_linux-opt/testlogs/tensorflow/go/test/test.log

Executed 1 out of 634 tests: 84 tests pass, 549 fail to build and 1 fails locally. 
There were tests whose specified size is too big. Use the --test_verbose_timeout_warnings command line option to see which ones these are.

de plus, à la fois mon CPU et le GPU semblent "non testé" à ComputeCPP selon co mputecpp_info.

Answer 1

Pour surmonter la première erreur, essayez -//tensorflow/go/... - nous n'avons pas encore essayé le wrapper go.

L'erreur XLA est source de confusion car dans le script crosstool, nous évitons explicitement de compiler le dossier "compilateur" avec ComputeCpp (https://github.com/lukeiwanski/tensorflow/blob/dev/eigen_mehdi/third_party/sycl/crosstool/computecpp.tpl#L46).

Assurez-vous que vous êtes sur cette branche: https://github.com/lukeiwanski/tensorflow/tree/dev/eigen_mehdi
