英文:
array.array() takes no keyword arguments
问题
在FARS数据集上尝试进行k均值聚类时，出现了array.array()不接受关键字参数的错误，不理解为什么或如何更正它。
最初出现int32错误，我将其更改为np.int32，问题得到解决，但现在出现了array错误，无法弄清楚如何修复。
完整错误信息：
TypeError: array.array()不接受关键字参数代码：X = np.array([[1, 2], [1, 4], [1, 0],[10, 2], [10, 4], [10, 0]])kmeans = KMeans(n_clusters=2, random_state=0, n_init="auto").fit(X)kmeans.labels_array([1, 1, 1, 0, 0, 0], dtype=np.int32)kmeans.predict([[0, 0], [12, 3]])array([1, 0], dtype=np.int32)kmeans.cluster_centers_array([[10., 2.],[ 1., 2.]])
希望这能帮助您解决问题。

Trying to do a k means clustering on FARS dataset, getting the array.array() takes no keyword arguments error and don't understand why or how to correct it.
Initially was getting errors for int32 which I changed to np.int32 and that corrected but now I am getting the array error and can't figure out how to fix it.

不要将您的代码直接复制/粘贴，因为某些行是前一行的输出。这些行不应用作语句：
>>> kmeans.labels_
array([1, 1, 1, 0, 0, 0], dtype=np.int32) # 这是 kmeans.labels_ 的输出
>>> kmeans.predict([[0, 0], [12, 3]])
array([1, 0], dtype=np.int32) # 这是 kmeans.predict(...) 的输出
>>> kmeans.cluster_centers_
array([[10., 2.], # 这是 kmean.cluster_centers_ 的输出
[ 1., 2.]])
代码应为：
import numpy as np
from sklearn.cluster import KMeans
X = np.array([[1, 2], [1, 4], [1, 0],
[10, 2], [10, 4], [10, 0]])
kmeans = KMeans(n_clusters=2, random_state=0, n_init="auto").fit(X)
labels = kmeans.labels_
preds = kmeans.predict([[0, 0], [12, 3]])
centroids = kmeans.cluster_centers_
用法：
>>> labels
array([1, 1, 1, 0, 0, 0], dtype=int32)
>>> preds
array([1, 0], dtype=int32)
>>> centroids
array([[10., 2.],
[ 1., 2.]])

英文:
Don't copy/paste your code as it, some lines are the output of the previous line. This lines are not intended to be used as statements:
>>> kmeans.labels_array([1, 1, 1, 0, 0, 0], dtype=np.int32) # this is the output of kmeans.labels_>>> kmeans.predict([[0, 0], [12, 3]])array([1, 0], dtype=np.int32) # this is the output of kmeans.predict(...)>>> kmeans.cluster_centers_array([[10., 2.], # this is the output of kmean.cluster_centers_[ 1., 2.]])
The code should be:
import numpy as npfrom sklearn.cluster import KMeansX = np.array([[1, 2], [1, 4], [1, 0],[10, 2], [10, 4], [10, 0]])kmeans = KMeans(n_clusters=2, random_state=0, n_init="auto").fit(X)labels = kmeans.labels_preds = kmeans.predict([[0, 0], [12, 3]])centroids = kmeans.cluster_centers_
Usage:
>>> labelsarray([1, 1, 1, 0, 0, 0], dtype=int32)>>> predsarray([1, 0], dtype=int32)>>> centroidsarray([[10., 2.],[ 1., 2.]])
