Google Colab ModuleNotFoundError：没有名为“sklearn.externals.joblib”的模块

Question

我的初始导入看起来像这样，这个代码块运行良好。

# Libraries to help with reading and manipulating data
import numpy as np
import pandas as pd

# Libraries to help with data visualization
import matplotlib.pyplot as plt
import seaborn as sns

sns.set()

# Removes the limit for the number of displayed columns
pd.set_option("display.max_columns", None)
# Sets the limit for the number of displayed rows
pd.set_option("display.max_rows", 200)

# to split the data into train and test
from sklearn.model_selection import train_test_split

# to build linear regression_model
from sklearn.linear_model import LinearRegression

# to check model performance
from sklearn.metrics import mean_absolute_error, mean_squared_error, r2_score

但是当我尝试执行命令时，我收到错误 ModuleNotFoundError: No module named 'sklearn.externals.joblib'

我尝试使用.pip 来安装所有模块和其他针对此错误的建议，但它不起作用。 这是 google colab 所以不知道我错过了什么

import joblib
from mlxtend.feature_selection import SequentialFeatureSelector as SFS

您的代码在 colab 上对我来说很好，我建议只使用这个块打开一个新实例并重试。
