导入错误：无法从“darts.models”导入名称“MovingAverage”

Question

当我尝试导入 MovingAverage 时，出现导入错误。

ImportError: cannot import name 'MovingAverage' from 'darts.models' (/usr/local/lib/python3.10/dist-packages/darts/models/__init__.py)

当然，我确实安装了darts。

!pip install darts

这是源代码片段

from darts.models import MovingAverage
# Oil Price

oil = TimeSeries.from_dataframe(df_oil, time_col = 'date', value_cols = ['dcoilwtico'], freq = 'D')

oil = oil.astype(np.float32)

# Transform
oil_filler = MissingValuesFiller(verbose=False, n_jobs=-1, name="Filler")
oil_scaler = Scaler(verbose=False, n_jobs=-1, name="Scaler")
oil_pipeline = Pipeline([oil_filler, oil_scaler])
oil_transformed = oil_pipeline.fit_transform(oil)

# Moving Averages for Oil Price
oil_moving_average_7 = MovingAverage(window=7)
oil_moving_average_28 = MovingAverage(window=28)

Answer 1

darts是什么版本？

pip show darts

我建议首先检查您安装的 darts 版本，并确保它是最新版本或包含 MovingAverage 类的版本。

这是我运行代码片段的输出，运行后解决了导入错误

!pip install darts
