nltk中meteor score的計算，報錯

懶得在介紹來龍去脈了，反正就是找到的**全是這種：

import nltk

hypothesis = ' '.join(['it', 'is', 'a', 'cat', 'at', 'room'])
reference = ' '.join(['it', 'is', 'a', 'cat', 'inside', 'the', 'room'])
#there may be several references
merteor_score = nltk.translate.meteor_score.single_meteor_score(reference, hypothesis)
print(merteor_score)
簡單來說就是hypothesis和reference都是字串，然後我就一直報這個錯：typeerror: "hypothesis" expects pre-tokenized hypothesis (iterable[str]): it is a cat at room。看起來是型別問題，然後找了一通，全都是用的字串，最後沒辦法了看了眼原始碼，說要求是格式，我覺得應該是set型別吧，然後就把

hypothesis和reference改成了set，然後就可以了，就emmm，我還費勁巴拉改一晚上，難道是nltk版本更新所以資料格式換了？

改後**：

import nltk

# from nltk.corpus import wordnet
# nltk.download('wordnet')
hypothesis = ['it', 'is', 'a', 'cat', 'at', 'room']
reference = ['it', 'is', 'a', 'cat', 'inside', 'the', 'room']
hypothesis=set(hypothesis)
reference=set(reference)
#there may be several references
merteor_score = nltk.translate.meteor_score.single_meteor_score(reference, hypothesis)
print(merteor_score)

python中首次安裝使用nltk

1.在cmd命令提示符視窗中輸入 pip install nltk 2.首次輸入python 時，import nltk text welcome readers.i hope you find it interesting.please do reply.需要加空格 from nltk.token...
