我正在尝试探索tensorflow android演示。我想使用android studio调整应用程序。
然而，当我只是遵循instructions时，无论我做什么，我都会遇到编译错误：
尝试使用bazel和NDK r12b编译tensorflow：
$bazel build -c opt //tensorflow/examples/android:tensorflow_demo
ERROR: /home/myUser/libs/tensorflow_android/WORKSPACE:3:1: //external:io_bazel_rules_closure: no such attribute 'urls' in 'http_archive' rule.
ERROR: /home/myUser/libs/tensorflow_android/WORKSPACE:3:1: //external:io_bazel_rules_closure: missing value for mandatory attribute 'url' in 'http_archive' rule.
ERROR: com.google.devtools.build.lib.packages.BuildFileContainsErrorsException: error loading package '': Encountered error while reading extension file 'closure/defs.bzl': no such package '@io_bazel_rules_closure//closure': error loading package 'external': Could not load //external package.

尝试在bazel后编译较新版本的this advice：
$bazel version
Build label: 0.2.3-jdk7 // This is my current version of bazel
通过apt-get：
$sudo apt-get upgrade bazel

来源（试过bazel-0.4.2和bazel-0.5.0）：
$./compile.sh
INFO: You can skip this first step by providing a path to the bazel binary as second argument:

Building Bazel from scratch
ERROR: JDK version (1.7) is lower than 1.8, please set $JAVA_HOME.
或
$bazel build //src:bazel

allow_files should be a boolean or a filetype object.

切换java版本以查看bazel编译问题是否来自那里：
$sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-8-oracle/jre/bin/java 1074 auto mode
1 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode
* 2 /usr/lib/jvm/java-7-oracle/jre/bin/java 1072 manual mode
3 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1069 manual mode
4 /usr/lib/jvm/java-8-oracle/jre/bin/java 1074 manual mode
到目前为止没有运气： - /。有没有人从源代码成功编译android的tensorflow？
什么版本的Tensorflow，NDK，bazel，java是彼此需要/兼容的？我真的需要bazel吗？ （从来没有用过它）我不能像在任何其他应用程序一样在android-studio中编译android演示吗？
我使用的是Ubuntu 14.04，Cuda8.0，cudnn_v5.1，Titan X Pascal（不确定这些事情是否重要）
