Centos7下的nltk啟動(dòng)問題
CentOS 7， Python 3.6，ipython 6.0.0
問題描述
ipython
啟動(dòng)ipython命令
import nltk
爆出以下的錯(cuò)誤信息：
In [1]: import nltk --------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last)in () ----> 1 import nltk /opt/python36env/lib/python3.6/site-packages/nltk/__init__.py in () 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 () 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 () 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 () 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 () 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 () 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 () 21 # 3.

從錯(cuò)誤信息來分析，可以發(fā)現(xiàn)，就是sqlite3找不到而已。
問題分析與解決
那就嘗試看看sqlite3是否已經(jīng)安裝：
yum search sqlite3

找到了sqlite3-devel，那就安裝好了
yum install sqlite-devel
yum install sqlite-devel Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package sqlite-devel.x86_64 0:3.7.17-8.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ===================================================================================================================================================================================== Package Arch Version Repository Size ===================================================================================================================================================================================== Installing: sqlite-devel x86_64 3.7.17-8.el7 base 104 k Transaction Summary ===================================================================================================================================================================================== Install 1 Package Total download size: 104 k Installed size: 366 k Is this ok [y/d/N]: y Downloading packages: sqlite-devel-3.7.17-8.el7.x86_64.rpm | 104 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : sqlite-devel-3.7.17-8.el7.x86_64 1/1 Verifying : sqlite-devel-3.7.17-8.el7.x86_64 1/1 Installed: sqlite-devel.x86_64 0:3.7.17-8.el7 Complete!
問題沒有解決
重新啟動(dòng)ipython
import nltk
但是問題依然存在，哪里出的問題呢？
問題最終解決
雖然安裝了sqlite3的數(shù)據(jù)庫，但是對(duì)于ipython的環(huán)境來說，確實(shí)無法找到sqlite3。
于是，我重新編譯，并且安裝了一下python3。
注意： 這個(gè)是在sqlite3安裝成功之后，在安裝python的運(yùn)行環(huán)境。
于是重新啟動(dòng)ipython，問題消逝，一切正常，本質(zhì)上就是sqlite3的安裝，以及sqlite3與python運(yùn)行環(huán)境之間的匹配的問題。
