树莓派安装TensorFlow

1. 树莓派和TensorFlow syste version不匹配
   1. 树莓派system “version 2018-11-13-raspbian-stretch.zip” 
   2. TensorFlow systemversion “tensorflow-1.11.0-cp35-none-linux_armv7l.whl”
   3. 这样在安装时出现错误      File "/usr/share/python-wheels/urllib3-1.19.1-py2.py3-none-any.whl/urllib3/util/retry.py", line 315, in increment total -= 1TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'
2. 已知安装成功
   1. 树莓派system “version 2018-11-13-raspbian-stretch.zip” 
   2. TensorFlow systemversion “tensorflow-1.9.0-cp35-none-linux_armv7l.whl”
   3. 安装tensorflow

      首先安装tensorflow所需要的依赖库和工具

          sudo apt-get update
           
          # For Python 2.7
          sudo apt-get install python-pip python-dev
           
          # For Python 3.3+
          sudo apt-get install python3-pip python3-dev

      然受按装tensorflow：

      如果之前没有安装过其他版本的tensorflow，直接：

          # For Python 2.7
          sudo pip install tensorflow-1.8.0-cp27-none-linux_armv7l.whl
           
          # For Python 3.4
          sudo pip3 install tensorflow-1.8.0-cp35-none-linux_armv7l.whl

      如果之前安装过其他版本的tensorflow，先卸载，再安装

          sudo pip3 uninstall tensorflow
          sudo pip3 install --upgrade tensorflow-1.8.0-cp35-none-linux_armv7l.whl

      完成！

   4.  

      测试

       

      pi@raspberrypi:~ $ python3
      Python 3.5.3 (default, Sep 27 2018, 17:25:39)

      '1.9.0'
      

      欢迎来到TensorFlow
