無法編譯tensorflow所需的bazel-android

我正在嘗試探索tensorflow android演示。我想使用android studio修改應用程序。無法編譯tensorflow所需的bazel-android

然而，當我只需按照instructions我得到的編譯錯誤，無論我做什麼：

嘗試使用巴澤爾和NDK R12B編譯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. 
INFO: Elapsed time: 0.129s

嘗試編譯的bazel較新版本以下this advice：

$bazel version 
Build label: 0.2.3-jdk7 // This is my current version of bazel

通過

apt-get的：

$sudo apt-get upgrade bazel 
Reading package lists... Done 
Building dependency tree  
Reading state information... Done 
Calculating upgrade... Done 
E: Unable to locate package bazel

從源（試過巴澤勒-0.4.2和巴澤爾-0.5.0）：

$./compile.sh 
INFO: You can skip this first step by providing a path to the bazel binary as second argument: 
INFO: ./compile.sh compile /path/to/bazel 
    Building Bazel from scratch 
ERROR: JDK version (1.7) is lower than 1.8, please set $JAVA_HOME.

或

$bazel build //src:bazel 
ERROR: /home/myUser/libs/bazel/bazel-0.4.2/tools/build_rules/genproto.bzl:45:16: Traceback (most recent call last): 
    File "/home/myUser/libs/bazel/bazel-0.4.2/tools/build_rules/genproto.bzl", line 42

切換aroung Java的版本看巴澤爾是否編制問題來自那裏：

$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

到目前爲止沒有運氣： - /。有沒有人從源碼成功編譯android的tensorflow？

什麼版本的Tensorflow，NDK，bazel，java是必需的/兼容的？我真的需要bazel嗎？（無論如何，從來沒有使用過）我不能像任何其他應用程序一樣在android-studio中編譯android演示程序嗎？我使用Ubuntu 14.04，Cuda8.0，cudnn_v5.1，泰坦X帕斯卡（不知道這些事情無關緊要）

嗨，你可以嘗試用一個較新版本的巴澤爾？ 0.2.3是一個非常舊的版本。最新版本是0.5.1 – Steren

0.2.3是我的系統上當前安裝的版本。我試圖編譯的版本（從github獲取）是0.5.0和0.5.1 – mcExchange

爲什麼你需要編譯它？在Ubuntu上安裝Bazel可以在不編譯的情況下完成。請遵循以下專用文檔：[在Ubuntu上安裝Bazel]（https://bazel.build/versions/master/docs/install-ubuntu.html） – Steren

在Ubuntu上安裝巴澤勒

可以不編制完成。

按照專用文檔中的所有步驟：Install Bazel on Ubuntu

我又試了一次。現在它的工作。謝謝，併爲模糊感到遺憾。 – mcExchange

還發現在安裝新的bazel之後，舊的仍然位於'〜/ bin'目錄下的$ PATH中，它隱藏了'/ usr/bin/bazel'下的新版本 – mcExchange
