解释 n_components (int): The number of mixture components for the model tol (float): The threshold at which convergence is determined to have been attained when fitting the model. reg_covar (float): A regularization value added to the diagonal of the covariance matrices for numerical stability.

指定 n_components (int)：代表模型中混合组件的数量；tol (float)：拟合模型时，达到收敛的阈值；reg_covar (float)：为了数值稳定性，添加到协方差矩阵的对角线的正则化值。
