KMeans报错AttributeError: 'NoneType' object has no attribute 'split'

KMeans报错AttributeError: 'NoneType' object has no attribute 'split'是因为在使用KMeans()函数时,参数n_clusters设置为1,而KMeans算法要求至少有两个簇。当n_clusters=1时,KMeans算法无法进行聚类分析,因此会出现报错。\[1\]
为了解决这个问题,你可以将n_clusters的值设置为大于等于2的整数,以确保KMeans算法能够正常运行。例如,你可以将n_clusters设置为2,即将数据分为两个簇进行聚类分析。\[2\]
以下是一个示例代码片段,展示了如何使用KMeans算法进行聚类分析,并避免了报错:
```python
from sklearn.cluster import KMeans
X1 = data\[\['Age', 'Spending Score (1-100)', 'Annual Income (k$)'\]\].values
inertia = \[\]
for n in range(2, 11):
algorithm = KMeans(n_clusters=n, init='k-means++', n_init=10, max_iter=300, tol=0.0001, random_state=111, algorithm='elkan')
algorithm.fit(X1)
inertia.append(algorithm.inertia_)
```
在上述代码中,将n_clusters的范围设置为2到10,避免了n_clusters为1时的报错。通过迭代不同的k值,可以使用手肘图来确定最优的k值。\[2\]
希望这个解答能够帮助到你!如果还有其他问题,请随时提问。
