本文主要讲解JDK、SDK、eclipse-adt、android studio、cpu模式TensorFlow 的安装配置。update:2019-08-30 03:31:46

JDK

当前系统jdk为openjdk10，导致很多旧版工具无法使用。发现/usr/lib/jvm里面有其他版本。
用sudo update-alternatives --config java切换成最低的，保证兼容性。

$ sudo update-alternatives --config java There are 3 choices for the alternative java (providing /usr/bin/java).    Selection    Path                                            Priority   Status ------------------------------------------------------------ * 0            /usr/lib/jvm/java-10-openjdk-amd64/bin/java      1101      auto mode   1            /usr/lib/jvm/java-10-openjdk-amd64/bin/java      1101      manual mode   2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode   3            /usr/lib/jvm/java-9-openjdk-amd64/bin/java       1091      manual mode  Press <enter> to keep the current choice[*], or type selection number: 2         update-alternatives: using /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java to provide /usr/bin/java (java) in manual mode $ java -version openjdk version "1.8.0_171" OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-2-b11) OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

ORACLE版的JAVA官网把旧版链接给关了，最近意外找到一个java8的下载地址。
IBM版的JAVA链接倒是挺全，下载位置在这里。
具体上面三个版本差异不作深究，目前保证openjdk8能用即可。

sdk

sudo apt-get install android*
这里有个问题，后面的android studio配置sdk时，普通用户会遇到目录无法写入的情况，不知道通用的办法是如何解决的。采取的临时方案是更改/usr/share/android-sdk目录的所有者权限：
sudo chown -R $(whoami):$(whoami) /usr/share/android-sdk
如有更好的方法，后续于此更新。

手机连接后，adb devices提示：no permissions (udev requires plugdev group membership)，解决步骤在这里。

eclipse-adt

不要使用apt install 安装，那个版本的一堆问题。从网上下载集成版的，解压使用。
遇到问题：error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory.
解决方案： sudo apt-get install lib32z1

android studio

下载前先开1antern，这个时候，android-sdk的代理界面要确保清空，以防干扰，终端输入android，配置如图：
去https://developer.android.com/studio/下载安装包，然后解压到指定目录
启动 ~/android-studio/bin/studio.sh ，新建项目，初始化设置
如果gradle从dl.google.com下载时始终404，在站长之家的ping测试页面找几个ip，添加到/etc/hosts里面。
接下来等待进度条跑完就可以了，没有喝咖啡的习惯，那就来包泡面先……

最后，别忘了关灯：ALT+F2、killall lantern，回车。

备用方案：

代理地址:mirrors.neusoft.edu.cn 端口：80
离线下载gradle，不过版本不好控制匹配，不推荐。

TensorFlow cpuģʽ

apt-get install python-pip python-dev -y pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.12.1-cp27-none-linux_x86_64.whl

测试下：

>>> import tensorflow as tf >>> hello = tf.constant('Hello, TensorFlow!') >>> sess = tf.Session() >>> print(sess.run(hello)) Hello, TensorFlow! >>> a = tf.constant(10) >>> b = tf.constant(32) >>> print(sess.run(a+b)) 42 >>>
