Google Colab ModuleNotFoundError：沒有名為“sklearn.externals.joblib”的模塊

Question

我的初始導入看起來像這樣，這個代碼塊運行良好。

# 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

但是當我嘗試執行命令時，我收到錯誤 ModuleNotFoundError: No module named 'sklearn.externals.joblib'

我嘗試使用.pip 來安裝所有模塊和其他針對此錯誤的建議，但它不起作用。 這是 google colab 所以不知道我錯過了什么

import joblib
from mlxtend.feature_selection import SequentialFeatureSelector as SFS

您的代碼在 colab 上對我來說很好，我建議只使用這個塊打開一個新實例並重試。
