[英]YellowBrick ImportError: cannot import name 'safe_indexing' from 'sklearn.utils'
[英]ImportError: cannot import name 'safe_indexing' from 'sklearn.utils'
每當我嘗試運行以下代碼行時:
from imblearn.under_sampling import NearMiss
對於 Jupyter 筆記本上的欠采樣(或過采樣)不平衡數據,我收到此錯誤:
ImportError Traceback (most recent call last)

ImportError: cannot import name 'safe_indexing' from 'sklearn.utils' (C:\Users\anaconda3\lib\site-packages\sklearn\utils\__init__.py)
對於 imblearn.under_sampling,您是否嘗試重新安裝 package?:
pip install imbalanced-learn
康達:
conda install -c conda-forge imbalanced-learn
在 jupyter 筆記本中:
import sys
!{sys.executable} -m pip install <package_name>
If you have scikitlearn>=0.24 (as far as i see there is a dependency for imblearn now,as scikit-learn (>=0.23) https://imbalanced-learn.org/stable/install.html ) you may want to try:
try:
from sklearn.utils import safe_indexing
except ImportError:
from sklearn.utils import _safe_indexing
編輯..\Anaconda3\Lib\site-packages\sklearn\utils\ __init__.py
。
復制def _safe_indexing...
直到下一個def
並將代碼重命名為def safe_indexing...
。
保持以前_safe_indexing
。
它以這種方式解決了這個問題。
在~\Anaconda3\Lib\site-packages\yellowbrick\classifier\threshold.py
模塊中替換:
from sklearn.utils import indexable, safe_indexing
和
from sklearn.utils import indexable, _safe_indexing
之后,重新啟動 kernel。
