由于目前的TensorFlow版本比较老旧导致很多算法和语法不通用编译报错，且没有几个贴详细说明如何在arm64上安装TensorFlow，借此为理由，写下人生第一个博客和firefly帖子。

注意，安装的过程中会自动下载必须的包，需要连接好网络。脱机安装很可能失败。
1.安装必要的python环境
- <font color="Black">sudo apt-get install libpython3.5-dev wget python3-pip python3-dev python3.5</font>
2.下载和安装别人编译好的arm（aarch64）版本tensorflow（因为自己编译需要配大量环境和占用很多资源，对于嵌入式板上编译就变得非常不可能，且现有的方法更为简便）
网上有别人编译好的TensorFlow，找到相应的文件。https://github.com/lhelontra/tensorflow-on-arm/releases
 
- #使用wget下载tensorflow-1.9.0-cp35-none-linux_aarch64.whl到当前目录
- #命名规则：cp35对赢python3.5，aarch64表示架构信息
- wget https://github.com/lhelontra/tensorflow-on-arm/releases/download/v1.9.0/tensorflow-1.9.0-cp35-none-linux_aarch64.whl
- #必须制定使用python3.5安装tensorflow-1.9.0-cp35-none-linux_aarch64.whl
- sudo python3.5 -m pip install tensorflow-1.9.0-cp35-none-linux_aarch64.whl
到此为止，TensorFlow已经安装完成了
3.修改python默认为python3.5
为了因为C++调用python时，默认是调用python2.7，这导致很多python3.5的语法报错。所以需要更改python默认软连接
- firefly@firefly:~/opencv-3-2$ python
- Python 3.5.2 (default, Nov 23 2017, 16:37:01)
- [GCC 5.4.0 20160609] on linux
- Type "help", "copyright", "credits" or "license" for more information.
- >>> import tensorflow as tf
- >>> hello = tf.constant('Hello world!')
- >>> sess = tf.Session()
- >>> print(sess.run(hello))
- b'Hello world!'
- firefly@firefly:~/opencv-3-2$ python
- Python 3.5.2 (default, Nov 23 2017, 16:37:01)
- [GCC 5.4.0 20160609] on linux
- Type "help", "copyright", "credits" or "license" for more information.
- >>> import tensorflow as tf
- >>> hello = tf.constant('Hello world!')
- >>> sess = tf.Session()
- >>> print(sess.run(hello))
- b'Hello world!'
4.出现的错误
有时候可能会出现缺少库额问题 bstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /usr/local/lib/python3.5/dist-packages/tensorflow/python/_pywrap_tensorflow_internal.so
