在我可以接受的所有建议之后，没有名为“sklearn.neighbors.base”的模块仍然存在

Question

I learned a lot of solutions from this website, but still cannot solve the problem. My code is as follows for your review:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import missingno as msno
import altair as alt
from statsmodels.graphics.mosaicplot import mosaic
from scipy.stats import chi2_contingency
import plotly.express as px
from pandas.plotting import parallel_coordinates
from wordcloud import WordCloud
import networkx as nx
from networkx.drawing.nx_agraph import graphviz_layout
from scipy.spatial import distance
!pip install sklearn
from sklearn.experimental import enable_iterative_imputer
from sklearn.impute import IterativeImputer
from sklearn.impute import KNNImputer
from missingpy import MissForest
import sklearn.neighbors._base
sys.modules['sklearn.neighbors.base'] = sklearn.neighbors._base
import warnings
warnings.filterwarnings("ignore")

And still shows the error: ModuleNotFoundError: No module named 'sklearn.neighbors.base' I've tried to do the follows:

pip install -U imbalanced-learn; pip install -U scikit-learn

ans there was still of no use

Answer 1

Finally, I solved the problem!!

I should write this before import missingpy, not behind it.

import sklearn.neighbors._base
import sys
sys.modules['sklearn.neighbors.base'] = sklearn.neighbors._base
from missingpy import MissForest

done.

Answer 2

this works fine for me

import sklearn.neighbors._base
