AttributeError：类型对象“sklearn.manifold._barnes_hut_tsne.array”没有属性“__reduce_cython__”

Question

I'm trying to run a code in Python to import Kmeans using sklearn. However, when I try to import, I get this error message:

AttributeError: type object 'sklearn.manifold._barnes_hut_tsne.array' has no attribute ' reduce_cython '

sklearn is installed with all the necessary packages. I'm unsure as to what the problem might be. Here is part of the code from my work involving the import:

from sklearn.cluster import KMeans
num_clusters = 8
km = KMeans(n_clusters=num_clusters)
%time km.fit(tfidf_matrix)
clusters = km.labels_.tolist()

even if I put from sklearn.cluster import KMeans all by itself, I get the same error, so the error is coming from that line of code alone. Any help would be appreciated.

NOTE: I am using Jupyter Notebook and yes, I have installed any and all necessary packages as well as updated sklearn.

Just uninstalled scipy and installed it again and restarted the kernel and then run the code. It worked for me. Basically it is due to the Kernel restart issue.
