question

Import “sklearn.model_selection” could not be resolved from source

Analysis && Solution

This is a code completion/Intelligent suggestion error in an IDE (such as VS Code), not a runtime error. It indicates a problem with Pylance (VS Code’s…).
The Python extension could not find the source code for the sklearn.model_selection module, therefore it cannot provide features such as auto-completion and jump to definitions.

could not be resolved from source
Possible reasons:

• The scikit-learn package is not installed correctly/not installed.
• Perform a check using pip list | findstr scikit-learn@[TOC]

Import “sklearn.model_selection” could not be resolved from source

分析&&解决

这是一个 IDE（如 VS Code）中的代码提示/智能感知错误，而不是程序运行时的错误。它表示 Pylance（VS Code 的
Python 扩展）无法找到 sklearn.model_selection 模块的源码位置，所以不能提供自动补全、跳转定义等功能。‘

could not be resolved from source
可能的原因：

• 没有正确/没有安装该包 scikit-learn 没有安装
  • 做检查 pip list | findstr scikit-learn ；conda list scikit-learn
• Python 环境配置错误 ，是不是你选错环境了。/选错了 错误的解释器（Python 解释器）（conda）

安装 conda install scikit-learn

重启vscode

检查是否还有该提示

要是还存在就不是没有安装的问题了
