decision_boundary = X_new[y_proba[:, 1] >= 0.5]会报ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (2,) + inhomogeneous part.的错误。需要改为decision_boundary = X_new[y_proba[:, 1] >= 0.5][0,0]
float("inf") 表示正无穷大，而在支持向量机（SVM）中，C 参数通常是一个正的浮点数，用于控制正则化的强度。将 C 设置为正无穷可能会导致数值不稳定或计算错误。
