我已经安装了sklearn，但是当我运行一个导入sklearn的python文件时，我得到了这个：

Traceback (most recent call last):
  File "first.py", line 3, in <module>
    from sklearn import datasets
ModuleNotFoundError: No module named 'sklearn'

这是我安装sklearn时的结果：

Requirement already satisfied: scikit-learn in c:\users\user\appdata\local\programs\python\python38\lib\site-packages (0.24.0)
Requirement already satisfied: numpy>=1.13.3 in c:\users\user\appdata\local\programs\python\python38\lib\site-packages (from scikit-learn) (1.19.4)
Requirement already satisfied: scipy>=0.19.1 in c:\users\user\appdata\local\programs\python\python38\lib\site-packages (from scikit-learn) (1.5.4)

如果你使用anaconda，你仍然可以使用pip来安装软件包：

pip install -U scikit-learn scipy matplotlib

对于Python 3.x，请用途：

pip3 install -U scikit-learn scipy matplotlib

首先，请确保您更新pip到最新版本：

python -m pip install --upgrade pip

然后尝试：

pip install -U scikit-learn" on widnows terminal (cmd)

或者用康达试试（如果你的PC上有的话）

conda install scikit-learn

还要确保你已经安装了numpy和scipy

pip install numpy

pip install scipy

“sklearn”已更改为“scikit-learn”，并且“sklearn”不再有效。
因此在终端中：

pip install -U scikit-learn
