ubuntu 从零安装tf-serving环境和opencv

参考官网：https://www.tensorflow.org/serving/setup

首先是安装gprc：

pip install grpcio  

然后发现没有安装pip，报错：
sudo: pip: command not found

好吧，那就先跳过这个，直接执行下一条语句：
sudo apt-get update && sudo apt-get install -y \
        build-essential \
        curl \
        libcurl3-dev \
        git \
        libfreetype6-dev \
        libpng12-dev \
        libzmq3-dev \
        pkg-config \
        python-dev \
        python-numpy \
        python-pip \
        software-properties-common \
        swig \
        zip \
        zlib1g-dev
ok以后，安装 serving api：
 pip install tensorflow-serving-api
报错：
Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

再尝试：pip install grpcio 还是报错：
Traceback (most recent call last):
  File "/usr/bin/pip", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
    locale.setlocale(locale.LC_ALL, '')
  File "/usr/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

网上查到解决方法：https://stackoverflow.com/questions/36394101/pip-install-locale-error-unsupported-locale-setting

just run the following command:

$ export LC_ALL=C

Long answer-

Here is my locale settings:

$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=C

怎么校验嫩？

Python2.7

    $ uname -a
    Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux
    $ python --version
    Python 2.7.9
    $ pip --version
    pip 8.1.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)
    $ unset LC_ALL
    $ pip install grpcio
    Traceback (most recent call last):
      File "/usr/local/bin/pip", line 11, in <module>
        sys.exit(main())
      File "/usr/local/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
        locale.setlocale(locale.LC_ALL, '')
      File "/usr/lib/python2.7/locale.py", line 579, in setlocale
        return _setlocale(category, locale)
    locale.Error: unsupported locale setting
    $ export LC_ALL=C
    $ pip install grpcio
就可以了

pip install tensorflow-serving-api  ok，可以，继续，这个是作为client的用的

接下来
echo "deb [arch=amd64] http://storage.googleapis.com/tensorflow-serving-apt stable tensorflow-model-server tensorflow-model-server-universal" | sudo tee /etc/apt/sources.list.d/tensorflow-serving.list

curl https://storage.googleapis.com/tensorflow-serving-apt/tensorflow-serving.release.pub.gpg | sudo apt-key add -

sudo apt-get update && sudo apt-get install tensorflow-model-server

这样 model  serving 和client 就都ok 啦

不过后面执行脚本中用到了opencv，所以这里也加下opencv的安装：

执行 Python ****.py时，报错：

    import cv2
ImportError: No module named cv2

安装：  pip install python-opencv 报错：

Collecting python-opencv
  Could not find a version that satisfies the requirement python-opencv (from versions: )
No matching distribution found for python-opencv
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

好吧，那就升级pip：

pip install --upgrade pip    然后在执行上面的还是没用，那就换个方式安装opencv了：

执行：

sudo apt-get install Python-OpenCV  安装了一大堆东西，还是没用

要放大招了： sudo apt-get install libopencv-dev

虽然安装了，但是还是没有用，看来只能大大招了：

sudo apt-get install python-opencv

然后可以了。。。。。这是什么鬼！！！！ 没发现倒数两个只是大小写问题吗！！！！！！！，我也是醉了。
