Centos7下的nltk启动问题

CentOS 7, Python 3.6,ipython 6.0.0

问题描述

ipython

启动ipython命令

import nltk

爆出以下的错误信息:

In [1]: import nltk---------------------------------------------------------------------------ModuleNotFoundError Traceback (most recent call last)<ipython-input-1-b06499430ee0> in <module>()----> 1 import nltk/opt/python36env/lib/python3.6/site-packages/nltk/__init__.py in <module>() 135 from nltk.translate import * 136 from nltk.sem import *--> 137 from nltk.stem import * 138 139 # Packages which can be lazily imported/opt/python36env/lib/python3.6/site-packages/nltk/stem/__init__.py in <module>() 27 from nltk.stem.isri import ISRIStemmer 28 from nltk.stem.porter import PorterStemmer---> 29 from nltk.stem.snowball import SnowballStemmer 30 from nltk.stem.wordnet import WordNetLemmatizer 31 from nltk.stem.rslp import RSLPStemmer/opt/python36env/lib/python3.6/site-packages/nltk/stem/snowball.py in <module>() 24 25 from nltk import compat---> 26 from nltk.corpus import stopwords 27 from nltk.stem import porter 28 from nltk.stem.util import suffix_replace/opt/python36env/lib/python3.6/site-packages/nltk/corpus/__init__.py in <module>() 64 from nltk.tokenize import RegexpTokenizer 65 from nltk.corpus.util import LazyCorpusLoader---> 66 from nltk.corpus.reader import * 67 68 abc = LazyCorpusLoader(/opt/python36env/lib/python3.6/site-packages/nltk/corpus/reader/__init__.py in <module>() 103 from nltk.corpus.reader.categorized_sents import * 104 from nltk.corpus.reader.comparative_sents import *--> 105 from nltk.corpus.reader.panlex_lite import * 106 107 # Make sure that nltk.corpus.reader.bracket_parse gives the module, not/opt/python36env/lib/python3.6/site-packages/nltk/corpus/reader/panlex_lite.py in <module>() 13 14 import os---> 15 import sqlite3 16 17 from nltk.corpus.reader.api import CorpusReader/usr/local/lib/python3.6/sqlite3/__init__.py in <module>() 21 # 3.

从错误信息来分析,可以发现,就是sqlite3找不到而已。

问题分析与解决

那就尝试看看sqlite3是否已经安装:

yum search sqlite3

找到了sqlite3-devel,那就安装好了

yum install sqlite-devel

问题没有解决

重新启动ipython

import nltk

但是问题依然存在,哪里出的问题呢?

问题最终解决

虽然安装了sqlite3的数据库,但是对于ipython的环境来说,确实无法找到sqlite3。

于是,我重新编译,并且安装了一下python3。

注意: 这个是在sqlite3安装成功之后,在安装python的运行环境。

于是重新启动ipython,问题消逝,一切正常,本质上就是sqlite3的安装,以及sqlite3与python运行环境之间的匹配的问题。
