sklearn.feature_extraction.text 中的语法无效

Question

我想在文本上应用 k-Means 聚类。我已经安装了 sklearn 包，但仍然在其中发现错误...我现在在下面的代码中遇到问题...它在第 1 行显示语法无效(sklearn.feature_extraction.text)

from sklearn.feature_extraction.text 
import TfidfVectorizer
from sklearn.cluster 
import KMeans
from sklearn.metrics 
import adjusted_rand_score

documents = ["This little kitty came to play when I was eating at a restaurant.",
             "Merley has the best squooshy kitten belly.",
             "Google Translate app is incredible.",
             "If you open 100 tab in google you get a smiley face.",
             "Best cat photo I've ever taken.",
             "Climbing ninja cat.",
             "Impressed with google map feedback.",
             "Key promoter extension for Google Chrome."]

vectorizer = TfidfVectorizer(stop_words='english')
X = vectorizer.fit_transform(documents)

true_k = 2
model = KMeans(n_clusters=true_k, init='k-means++', max_iter=100, n_init=1)
model.fit(X)

print("Top terms per cluster:")
order_centroids = model.cluster_centers_.argsort()[:, ::-1]
terms = vectorizer.get_feature_names()
for i in range(true_k):
    print("Cluster %d:" % i),
    for ind in order_centroids[i, :10]:
        print(' %s' % terms[ind]),
    print

print("\n")
print("Prediction")

Y = vectorizer.transform(["chrome browser to open."])
prediction = model.predict(Y)
print(prediction)

Y = vectorizer.transform(["My cat is hungry."])
prediction = model.predict(Y)
print(prediction)

问题是 { "message": "无效语法（第 1 行）",

}

Answer 1

我认为您的导入在语法上是关闭的，from...import 需要在一行中。

from sklearn.feature_extraction.text import TfidfVectorizer
from sklearn.cluster import KMeans
from sklearn.metrics import adjusted_rand_score

我现在仍然有这个问题：
