卸载tensorflow

    sudo pip uninstall tensorflow

安装git

    安装git时记得先安装，后更新系统

    sudo apt install git

安装jdk8:

    my@ubuntu:~$ java

    my@ubuntu:~$ sudo add-apt-repository ppa:openjdk/ppa

    my@ubuntu:~$ sudo add-apt-repository ppa:openjdk-r/ppa

 

    my@ubuntu:~$ sudo apt-get update

    my@ubuntu:~$ sudo apt-get install openjdk-8-jdk

    my@ubuntu:~$ sudo apt-get install openjdk-8-jre openjdk-8-jdk-headlesss

    

    my@ubuntu:~$ java -version

openjdk version "1.8.0_131"

OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-2ubuntu1.16.04.3-b11)

OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

Install Bazel：

    sudo apt-get update && sudo apt-get install bazel

    sudo apt-get upgrade bazel

    bazel version

一、安装virtualenv:

    my@ubuntu:~$ sudo apt-get install python-virtualenv

    在virtualenv中创建tensorfloe环境

    my@ubuntu:~$ virtualenv --system-site-packages ~/tensorflow

    激活tensorflow的virtualenv环境

    my@ubuntu:~$ source ~/tensorflow/bin/activate

    为虚拟环境创建快捷方式：

    sudo printf '\nalias tensorflow="source ~/tensorflow/bin/activate"'>>~/.bashrc

    让其生效：

    source ~/.bashrc

二、在env环境中

    

    git clone https://github.com/tensorflow/tensorflow

    sudo apt-get install python-numpy python-dev python-pip python-wheel

因为我的vm中没有gpu，省去gpu的配置环节：

    sudo apt-get install libcupti-dev

     sudo pip install six numpy wheel

Configuration finished

这里是非常重要的编译配置：可以参考http://blog.csdn.net/nicholas_wong/article/details/70215127，但还要结合自己的机器报的警告来配置，

我的机器报如下警告：

/cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE4.1 instructions, but these are available on your machine and could speed up CPU computations.  

W tensorflow/core/platform/cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE4.2 instructions, but these are available on your machine and could speed up CPU computations.  

W tensorflow/core/platform，那我安装的时候就配置sse4.1和sse4.2的选项，刚开始直接把人家的复制过来用，安装完后报错，后来自己配置了一下，安装成功。而且上面的警告有时候是不会出现的，

我在安装SyntaxNet wrapper 地址及安装：https://github.com/short-edition/syntaxnet-wrapper时报错，导致测试走不下去，只能消除警告，

    sudo bazel build -c opt  --copt=-msse4.1 --copt=-msse4.2  //tensorflow/tools/pip_package:build_pip_package

这个编译时间超长，要有耐心。

上述命令会生成一个叫做build_pip_package的脚本，按照如下命令运行这个脚本，在/tmp/tensorflow_pkg文件夹中创建pip的安装包：

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

    cd  /tmp/tensorflow_pkg

    ls

会发现一个whl的文件：tensorflow-1.3.0-cp27-cp27mu-linux_x86_64.whl，这是编译生成的。

下面进行安装：

    sudo  pip install /tmp/tensorflow_pkg/tensorflow-1.3.0-cp27-cp27mu-linux_x86_64.whl

安装完成后进行测试：注意测试的时候不要到安装目录下测试。

$ python

Enter the following short program inside the python interactive shell:

# Python

import tensorflow as tf

hello = tf.constant('Hello, TensorFlow!')

sess = tf.Session()

print(sess.run(hello))

If the system outputs the following, then you are ready to begin writing TensorFlow programs:

Hello, TensorFlow!

如果不报sse4.1和sse4.2错误，有可能安装成功。

安装syntaxnet:

    前提是tensorflow已经安装好，

    git clone --recursive https://github.com/tensorflow/models.git

    cd models/syntaxnet/tensorflow

配置选项：

    $ ./configure

(tensorflow) my@ubuntu:~/models/syntaxnet/tensorflow$ cd ..

    (tensorflow) my@ubuntu:~/models/syntaxnet$ bazel test syntaxnet/... util/utf8/...

    (tensorflow) my@ubuntu:~/models/syntaxnet$ chmod +x  syntaxnet/demo.sh

7、pip安装 asciitree、mock

    (tensorflow) my@ubuntu:~/models/syntaxnet$  pip install asciitree

    (tensorflow) my@ubuntu:~/models/syntaxnet$ pip install mock

    测试一个句子：

    (tensorflow) my@ubuntu:~/models/syntaxnet$ sudo  echo 'Bob brought the pizza to Alice.' | syntaxnet/demo.sh

    

测试中文：    

MODEL_DIRECTORY为解压的中文模型的位置，一种方式是从http://download.tensorflow.org/models/parsey_universal/Chinese.zip下载

然后解压到/home/py/models/syntaxnet/syntaxnet/models/parsey_universal，

另外一种方式是安装 A lightweight SyntaxNet wrapper 地址及安装：https://github.com/short-edition/syntaxnet-wrapper，它会自动安装语言模型

测试：

py@ubuntu:~/models/syntaxnet$ MODEL_DIRECTORY=/home/py/models/syntaxnet/syntaxnet/models/parsey_universal/Chinese

py@ubuntu:~/models/syntaxnet$ echo '然而,中国经历了30多年的改革开放' | syntaxnet/models/parsey_universal/tokenize_zh.sh $MODEL_DIRECTORY | syntaxnet/models/parsey_universal/parse.sh $MODEL_DIRECTORY

安装SyntaxNet Wrapper

直接复制文档了：

A lightweight SyntaxNet wrapper

The wrapper allows generic use of SyntaxNet in python. It provides interfaces for morphological analyse, pos tagging and dependency resolution along with optional formatting tool.

The wrapper does not intend to make any assumptions on the use of SyntaxNet, that's why it provides a simple interface and the raw output as default.

Disclaimer : Has been inspired from another wrapper but we did not want a server based wrapper.

Installation

We assume here that you have SyntaxNet installed and working properly on your workstation. If not, please refer to SyntaxNet official page

The wrapper has been tester on Ubuntu 14.04 Trusty and 16.04 Xenial.

(virtualenv)$ git clone https://github.com/short-edition/syntaxnet-wrapper.git

(virtualenv)$ cd syntaxnet-wrapper

(virtualenv)/syntaxnet-wrapper$ pip install -r requirements.txt

(virtualenv)/syntaxnet-wrapper$ vim syntaxnet_wrapper/config.yml

syntaxnet:

  ROOT_DIR: /home/user/workspace/syntactic_parser/tensorflow_models/syntaxnet

  PARSER_EVAL: bazel-bin/syntaxnet/parser_eval

  CONTEXT: syntaxnet/models/parsey_universal/context.pbtxt

  MODEL: syntaxnet/models/parsey_universal

(virtualenv)/syntaxnet-wrapper$ python -m unittest discover syntaxnet_wrapper

(virtualenv)/syntaxnet-wrapper$ pip install .

这一句比较重要：创建 /usr/share/syntaxnet_wrapper_config.yml，内容就是

syntaxnet:

  ROOT_DIR: /home/py/models/syntaxnet

  PARSER_EVAL: bazel-bin/syntaxnet/parser_eval

  CONTEXT: syntaxnet/models/parsey_universal/context.pbtxt

  MODEL: syntaxnet/models/parsey_universal

You should be able to use the wrapper from now. Instead of creating config.yml in the current folder, you can also expose it though the environment variable SYNTAXNET_WRAPPER_CONFIG or copying it in /usr/share/syntaxnet_wrapper_config.yml

You can also use the Dockerfile provided that will install SyntaxNet itself and the wrapper

How to use this wrapper

Two mode

You can use the wrapper in two modes, embodied in two different classes with the same interface

    SyntaxNetWrapperSubprocess, a python implementation of demo.sh shell script provided in SyntaxNet. It starts new subprocesses at each call.

    SyntaxNetWrapper, using wrapper's syntaxnet python implementation. Have the advantage to be faster and more memory efficient than the version with subprocesses. However, we are experience some trouble with it. See Well-known issues

The interface

The wrapper is expecting unicode text compatible with utf-8 format. The interface is the same for both classes :

    morpho_sentence, make morphological analyse for a single sentence

    morpho_sentences, make morphological analyse for a sentences list

    tag_sentence, make pos tagging for a single sentence

    tag_sentences, make pos tagging for a sentences list

    parse_sentence, make dependency parsing for a single sentence

    parse_sentences, make dependency parsing for a sentences list

    transform_morpho, transform_tag and transform_dependency format the outputs in a more readable form. Deleting unfilled field.

例子：

>>> from syntaxnet_wrapper.wrapper import SyntaxNetWrapper

>>> sn_wrapper = SyntaxNetWrapper()

>>> dependency_output = sn_wrapper.parse_sentence(u"Bob brought a pizza to Alice")

>>> print dependency_output

u'1\tBob\t_\tPROPN\tNNP\tNumber=Sing|fPOS=PROPN++NNP\t2\tnsubj\t_\t_\n2\tbrought\t_\tVERB\tVBD\tMood=Ind|Tense=Past|VerbForm=Fin|fPOS=VERB++VBD\t0\tROOT\t_\t_\n3\ta\t_\tDET\tDT\tDefinite=Ind|PronType=Art|fPOS=DET++DT\t4\tdet\t_\t_\n4\tpizza\t_\tNOUN\tNN\tNumber=Sing|fPOS=NOUN++NN\t2\tdobj\t_\t_\n5\tto\t_\tADP\tIN\tfPOS=ADP++IN\t6\tcase\t_\t_\n6\tAlice\t_\tPROPN\tNNP\tNumber=Sing|fPOS=PROPN++NNP\t4\tnmod\t_\t_\n\n'

Use of different language

The wrapper use by default english model but you can use every "Parsey Universal" released by Google. You just need to pass the name of the model as a constructor's argument. The wrapper will then automatically download the model and use it.

>>> sn_wrapper = SyntaxNetWrapper(language='French')
