KeyError:word2vec中的“单词'word'不在词汇表中" [英] KeyError: “word 'word' not in vocabulary” in word2vec

问题描述

我正在使用我训练过的维基语料word2vec，如果我输入的单词不在word2vec的词汇表中怎么办?

I am using word2vec, wiki corpus I trained, what can I do if the word I input not in vocabulary in word2vec?

稍作测试:

model = word2vec.Word2Vec.load('model/' + 'wiki_chinese_word2vec.model')    
model['boom']

错误:

KeyError(单词'％s'不在词汇中"％单词)

KeyError("word '%s' not in vocabulary" % word)

推荐答案

使用try& except用于处理Python中的异常. try块正常执行.如果发生任何异常或错误，则将执行except块.

Use try & except to handle exceptions in Python. try block executes normally. If any exception or error occurs then except block will be executed.

try:
        c = model['boom']
except KeyError:
        print "not in vocabulary"
        c = 0
