如何解决使用 linear_kernel 时 Scikit-learn 崩溃
我正在学习以下教程:
https://www.datacamp.com/community/tutorials/recommender-systems-python
当我尝试运行基于内容的推荐代码时,执行停止在终端上输出“Killed”,有人说这是内存不足问题。但是我的机器上有 16GB 的 RAM,我怀疑这会不会是个问题。
#Construct the required TF-IDF matrix by fitting and transforming the data
tfidf_matrix = tfidf.fit_transform(Metadata['overview'])
#Output the shape of tfidf_matrix
print(tfidf_matrix.shape)
#Array mapping from feature integer indices to feature name.
tfidf.get_feature_names()[5000:5010]
# Compute the cosine similarity matrix (THE LINE BELOW CRASHES)
cosine_sim = linear_kernel(tfidf_matrix,tfidf_matrix)
终端输出这个:

我试过改变
Metadata = pd.read_csv('movies_Metadata.csv',low_memory=False)
到
Metadata = pd.read_csv('movies_Metadata.csv',low_memory=True)
但这没有用。
我需要更改什么才能在不挂起的情况下执行代码?
