tensorflow android构建过程中bazel的错误

Question

我正在遵循以下教程https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/android

我使用后的错误

sudo bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package


ERROR: /home/hugo/.cache/bazel/_bazel_root/1c2dc229a3fb3a0c8f1a06862d6b4c74/external/local_config_cuda/crosstool/BUILD:4:1: Traceback (most recent call last):

    fail("ERROR: Building with --config=c...")

我假设上述错误也是由于我的bazel安装不正确造成的？我试了bazel版本

Build label: 0.4.5
Build target: bazel-out/local-fastbuild/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Thu Mar 16 12:19:38 2017 (1489666778)
Build timestamp: 1489666778
Build timestamp as int: 1489666778

所以我很确定它已经安装好了。这里的错误是什么？我如何纠正它？

Answer 1

错误：任务“：BuildExternalAssets”执行失败。启动进程“command”/usr/local/bin/bazel时出现问题

1.这表明在“/usr/local/bin/bazel”中找不到bazel，您清楚地理解了，正如您所说，“我检查了/usr/local/bin/并且那里没有bazel文件夹。”

2.请通过命令行中的“whereis bazel”命令检查bazel在PC上的安装位置（如果是Linux操作系统）

错误：使用--config=cuda构建，但是TensorFlow没有配置为使用GPU支持构建。

3.看起来你正在使用CUDA的目标源，这是你试图做的吗？我的意思是，你想编译源代码以部署在基于CUDA的设备上吗？

如果是，“请重新运行。/configure”
