nltk download出错Error connecting to server

Machine learning often uses python’s natural language processing framework NLTK. This is a commonly used package for machine learning. You will encounter many problems during use. I will share with you some of my experiences in this.

Today, let’s talk about the installation and the download error that occurred during the installation.

>>> import nltk

>>> nltk.download()

Packages:

Error connecting to server: [Errno -2] Name or service not known

After speculation, it is caused by the server being unable to connect to the download server address.

Check the nltk download configuration

Downloader> c

Data Server:

- URL:

- 3 Package Collections Available

- 74 Individual Packages Available

Local Machine:

- Data directory: /home /wym/nltk_data

Then

> curl http://nltk.googlecode.com/svn/trunk/nltk_data/index.xml

Error: curl: (6) Couldn't resolve host 'nltk.googlecode.com '

Google's address must have been blocked (alas, everyone knows)

Solution:

Modify the dns address,

> vim /etc/resolv.conf

Modify the nameserver to: nameserver 8.8.8.8

Problem Solved
