本文是对github上fork的xing_NLP中的用N-gram语言模型做完型填空这样一个NLP项目环境搭建的一个说明,本来写在README.md中。第一次用github中的wiki,想想尝试一下也不错,然而格式非常的混乱,自己都不满意,所以先在博客园记录一下,等github博客搭建成功了再说。
作为programer,linux自然是首先选择,ubuntu,centos等等都可以。我用的是CentOS7.3,之前用Centos6.5各种报错,建议装最新版的linux系统,何为最新版?2016年以后出的linxu系统。
相关问题,后续给出。
以下操作建议用root用户进行。
这里给出清华大学开源镜像下载链接:
[anacondapython2.7最新版清华链接](https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda2-4.4.0-Linux-x86_64.sh)
安装方法:
bash Anaconda2-4.4.0-Linux-x86_64.sh
pip install NLTK
安装完成后,要在NLTK里下载punkt这个包。

因为我这里安装过,所以出现已经是最新的说明。
这个是本文的重点,异常的复杂:
下面这个链接是官网关于依赖包的安装说明,可以看懂的,照官网来,看不懂的继续往下看:
[kenlm官网关于依赖包的安装说明:](https://kheafield.com/code/kenlm/dependencies/)
说明:安装kenlm之前一定要看一下gcc 的版本(gcc -v)版本一定要>=4.8.否则会报下列错误:
gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I. -I/root/anaconda2/include/python2.7 -c util/float_to_string.cc -o build/temp.linux-x86_64-2.7/util/float_to_string.o -O3 -DNDEBUG -DKENLM_MAX_ORDER=6 -std=c++11 -DHAVE_ZLIB
cc1plus: 警告:命令行选项“-Wstrict-prototypes”对 Ada/C/ObjC 是有效的,但对 C++ 无效
cc1plus: 错误:无法识别的命令行选项“-std=c++11”
error: command ‘gcc‘ failed with exit status 1
----------------------------------------
Command "/root/anaconda2/bin/python -u -c "import setuptools, tokenize;__file__=‘/tmp/pip-NDhcKC-build/setup.py‘;f=getattr(tokenize, ‘open‘, open)(__file__);code=f.read().replace(‘\r\n‘, ‘\n‘);f.close();exec(compile(code, __file__, ‘exec‘))" install --record /tmp/pip-GP5mEP-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-NDhcKC-build/`
cmake , xz, zlib , bzip2, boost (boost一定要放在最后安装,它要依赖前面的包)
(1)cmake的安装:因为我是Centos,这个我之前就有,采用yum安装的,编译安装也可以。(官网下载tar.gz,或者tar.bz)
yum install cmake
(2)xz的安装:官网下载最新的,以下给出的地址都是最新的。
wget http://tukaani.org/xz/xz-5.2.2.tar.gz
tar xzvf xz-5.2.2.tar.gz
cd xz-5.2.2
./configure
make
make install
(3)zlib的安装:
wget http://zlib.net/zlib-1.2.8.tar.gz
tar xzf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make install`
(4) bzip2的安装:
wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
tar xzvf bzip2-1.0.6.tar.gz
cd bzip2-1.0.6/
make
make install
(5)boost的安装:
wget https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.bz2
tar xjf boost_1_64_0.tar.bz2
./bootstrap.sh
./b2 install
说明这个我用源码编译安装出现问题,搞不定,现在将问题贴在这里,看到的可以一起解决一下:

那我最后是怎么搞定的呢?我用最简单的方法,yum安装:
yum install -y boost boost-devel boost-doc
前面的依赖包安装成功,那么这一步就水到渠成了:
weget http://kheafield.com/code/kenlm.tar.gz
cd kenlm
mkdir build
cd build
cmake ..
make
搞定!
