'numpy.ndarray' object has no attribute 'get'

发生AttributeError: 'numpy.ndarray' object has no attribute 'get'错误是因为numpy.ndarray对象没有get方法。通常情况下，get方法是用于从字典中获取值的，而不是从数组中获取值。在你提供的引用中，这个错误是由于在调用toarray()方法时出现的。该方法是将稀疏矩阵转换为稠密矩阵的方法，并不适用于numpy数组。解决这个问题的方法是将Xgroup_smote转换为稀疏矩阵，然后再使用toarray()方法将其转换为稠密矩阵。你可以按照引用中的修改代码进行操作。修改import scipy.sparse行并使用scipy.sparse.lil_matrix(Xgroup_smote).toarray()来替换Xgroup_smote = onehotencoder.fit_transform(Xgroup_smote).toarray()这一行。这样就可以避免'numpy.ndarray' object has no attribute 'get'错误的出现。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
