'GaussianMixture' object has no attribute 'covariances_'

'GaussianMixture' object has no attribute 'covariances_'

gmm = GaussianMixture(5)
gmm.means_ = np.array([[10], [20], [60], [80], [110]])
gmm.covars_ = np.array([[3], [3], [2], [2], [1]]) ** 2
gmm.weights_ = np.array([0.2, 0.2, 0.2, 0.2, 0.2])

X = gmm.sample(200000)
然后就报错 'GaussianMixture' object has no attribute 'covariances_'，请问这个怎么解决
