python-3.x - 导入错误 : cannot import name 'evaluate' ( from surprise import evaluate )

Question

from surprise import Reader, Dataset, SVD
from surprise import evaluate
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-12-6d771df269b8> in <module>()
----> 1 from surprise import evaluate

ImportError: cannot import name 'evaluate'

第一行，从惊喜导入阅读器，数据集，SVD 工作正常。
就是这样，它无法从惊喜包中导入评估。

我已经使用 conda 安装了 scikit-surprise。
我认为它已成功安装。

从 2020 年 1 月开始，请改为执行以下操作...

from surprise import SVD
from surprise import Dataset
from surprise.model_selection import cross_validate

# Load the dataset (download it if needed)
data = Dataset.load_builtin('ml-100k')

# Use the famous SVD algorithm
algo = SVD()

# Run 5-fold cross-validation and then print results
cross_validate(algo, data, measures=['RMSE', 'MAE'], cv=5, verbose=True)
