我正在使用sklearn，这是到目前为止的代码：
from sklearn.decomposition import LatentDirichletAllocation
lda_model = LatentDirichletAllocation(n_components=5, learning_method='online', max_iter=2
X_topics = lda_model.fit_transform(X)
topic_word = lda_model.components_
#vectorizer is from countVectorizer
y=vectorizerN.transform(["some text here"])
lda_model.transform(y)
array([[0.05000144, 0.05000128, 0.05000162, 0.05000113, 0.79999453]])
现在，它仅向我显示这5个概率，但是我怎么知道我的课程是什么？
