即使我已经安装了 sklearn，我也无法导入 sklearn

Question

我已经安装了 sklearn，但是当我运行导入 sklearn 的 python 文件时，我得到以下信息：

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)

Answer 1

“sklearn”已更改为“scikit-learn”，并且“sklearn”不再有效。

所以在终端中：

pip install -U scikit-learn
