Azure ML Error: TimeSeriesImputer object has no attribute '_known_df'

Question

运行 this orange juice sales notebook 我使用 .forecast() 方法得到以下错误。

代码

# The featurized data, aligned to y, will also be returned.
# This contains the assumptions that were made in the forecast
# and helps align the forecast to the original data
y_predictions, X_trans = fitted_model.forecast(X_test)

错误（full stacktrace）：

**AttributeError: 'TimeSeriesImputer' object has no attribute '_known_df'**

Answer 1
