報(bào)錯(cuò)如下:

raise ValueError("cannot index a corpus with zero features (you must specify either `num_features` or a non-empty corpus in the constructor)")
ValueError: cannot index a corpus with zero features (you must specify either `num_features` or a non-empty corpus in the constructor)

stackflow上轉(zhuǎn)過來的,驗(yàn)證有效,解決方案:

?index = similarities.MatrixSimilarity(corpus_tfidf)改為:

?index=similarities.Similarity(querypath,corpus_tfidf,len(dictionary))

總結(jié)

以上是生活随笔為你收集整理的ValueError: cannot index a corpus with zero features (you must specify either `num_features` or a no的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
