Question

这是我的代码：

mice=MICE(n_imputations=1, verbose=False, model=RandomForestRegressor())
df=pd.DataFrame(data=mice.complete(d), columns=d.columns, index=d.index)

一旦我在模型中放入一个scikit估算器，它就会出错。它也与XGBoost有关。

这是错误消息：

TypeError: fit() got an unexpected keyword argument 'inverse_covariance'

用RandomForest（）来完成bug的完全错误
