ImportError: cannot import name 'evaluate'
从意外导入的Reader,Dataset,SVD的第一行可以正常工作。 仅仅是这样,它就不能从Surprise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月起,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)
答案 1 :(得分:1)
根据文档,powershell.exe -window minimized -noexit -file "%USERPROFILE%\Desktop\UNB\script\UNBILLING.ps1"
方法为deprecated in version 1.0.5(功能上由model_selection.cross_validate()
代替),并且为removed in version 1.1.0,很可能是您已经安装的方法。
