我想我已经知道我的答案了，但是有很多比我更聪明和经验丰富的人，所以我想问一下。
当我尝试将我的hash_matrix (<class 'scipy.sparse.csr.csr_matrix'>)适配到AffinityPropagation时，我遇到了MemoryError。它仅在10,000个样本上失败，这在我的实际数据集范围内相对较小。
我的问题：我喜欢在较小的数据集上看到的AffinityPropagation的结果，但是除非我能够将其应用于我的大型数据集，否则它是无用的。
我的问题：在标准笔记本电脑上尝试适配数十万个项目到AffinityPropagation是否不太可能发生？
我了解到的：
AffinityPropagation不支持partial_fit和增量学习。- 时间复杂度是
AffinityPropagation的主要缺点。 Affinity Propagation [is] most appropriate for small to medium sized datasets.
抛出的错误：
Traceback (most recent call last):
