Question

我正在尝试导入以下库。导入sklearn时收到错误消息。我相信它与DLL路径有关，但我无法纠正它。我不想在代码中手动指定任何路径。请帮忙

代码：

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

from sklearn import preprocessing
%matplotlib inline

错误：

OSError: [WinError 126] The specified module could not be found

您可以尝试卸载 scipy，然后重新安装此特定版本。正如此特定 github 问题线程中所述，新版本的 scipy 存在问题。

pip uninstall scipy
pip install scipy==1.4.1
