Jeston tx1 Tensorflow 编译配置过程

首先要声明一下，本篇博文是编译tensorflow r0.9，如果你是想跑tensorflow版本的facenet,因为最新的model是基于tensorflowr0.11编译的，所以不会运行成功。本文也是踩了这个坑，只编译成功了r0.9。

参看链接：http://www.yuthon.com/2016/12/04/Installation-of-TensorFlow-r0-11-on-TX1/

Tensorflow编译：

你需要尽可能的删除一切东西，否则如果在本机编译，空间会不够，包很多错误，要么就给板子加个固态硬盘，要么就在移动硬盘下编译。建议编译的过程在代理下进行，如果你想编译r0.11版本，可参考上边第一个链接，本人没成功。

删除一切能删的：

   # get rid of liboffice, games, libvisionworks, perfkit, multimedia api, opencv4tegra, etc. 
    sudo apt-get purge libreoffice*
    sudo apt-get purge aisleriot gnome-sudoku mahjongg ace-of-penguins gnomine gbrainy
    sudo apt-get clean
    sudo apt-get autoremove

    rm -rf libvision*
    rm -rf PerfKit*

    # something along these lines; might be different for you
    # delete all libvision-works and opencv4tegra stuff
    cd var && rm -rf libopencv4tegra* && rm -rf libvision*

    # I deleted practically everything. Almost as if I shouldn't have even installed JetPack in the first place
    # delete all deb files, Firefox, chrome, all the stuff I really didn't need that was taking up memory. 
    # find big files and remove them assuming they're not important. Google is your friend.
    find / -size +10M -ls

另外在var下,有很多deb的包，可以都删除，会节约很多空间的。

安装protobuf,bazel与tensorflow:

    # install deps
    cd ~
    sudo add-apt-repository ppa:webupd8team/java
    sudo apt-get update
    sudo apt-get install oracle-java8-installer
    sudo apt-get install git zip unzip autoconf automake libtool curl zlib1g-dev maven swig bzip2

    #build  build protobuf 3.0.0-beta-2 jar
    git clone https://github.com/google/protobuf.git
    cd protobuf
    # autogen.sh downloads broken gmock.zip in d5fb408d
    git checkout master
    ./autogen.sh
    git checkout d5fb408d
    ./configure --prefix=/usr
    make -j 4
    sudo make install
    cd java
    mvn package

    #Get bazel version 0.2.1, it doesn't require gRPC 
    git clone https://github.com/bazelbuild/bazel.git
    cd bazel
    git checkout 0.2.1
    cp /usr/bin/protoc third_party/protobuf/protoc-linux-arm32.exe
    cp ../protobuf/java/target/protobuf-java-3.0.0-beta-2.jar third_party/protobuf/protobuf-java-3.0.0-beta-1.jar

编译：

   ./compile.sh

git tensorflow:

    ./configure
    # this will fail, but that's ok
    bazel build -c opt --config=cuda //tensorflow/tools/pip_package:build_pip_package

下载config,更新.cache:

    cd ~

    wget -O config.sub 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD'

编译：

    bazel build -c opt --config=cuda --local_resources 2048,4.0,1.0 --verbose_resources //tensorflow/tools/pip_package:build_pip_package --jobs 4

安装：

bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg

# The name of the .whl file will depend on your platform.
 sudo pip install /tmp/tensorflow_pkg/tensorflow-0.12.0rc0-py2-none-any.whl

下面是我编译好的tensorflow0.9版本：

链接: https://pan.baidu.com/s/1hrPd4FE 密码: qe5x

编译过程中可能会报错，多尝试几次，将jobs 换为3或4，编译过程中可能会报的错：

Error: unexpected EOF from Bazel server.

gcc: internal compiler error: Killed (program cc1plus)

这些都是因为内存不够，我是将deb全部删掉，在移动硬盘中编译，还碰到了cross_tool的错误，多换了几次jobs就成功了。

总之，这次的编译过程让我累死了，没啥收获。为了编译r0.11，还把0.9删了，结果0.9的安装包我还没保存，最后啥都没剩下。

点个赞咯，草稿快要写完时，没保存，火狐就崩了，又写了一遍，真倒霉，股市又因为加息的事大跌，虽然我两个月前就知道会这样，最近太忙，忘了卖，又亏惨了，我的人生啊！！！。。。。。

如果有人编译成功r0.11，请告诉下哈，本人不甘心。
