根据 Laci 要求编辑

1.Output 对于 jupyter kernelspec list:

Available kernels:
  python3    C:\Users\xxx\AppData\Roaming\jupyter\kernels\python3

2.Kernel.json内容：

{
 "argv": [
  "C:\Users\33826\Anaconda3\envs\tf_plates\python.exe",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3 (ipykernel)",
 "language": "python",
 "metadata": {
  "debugger": true
 }
}

3.Output 共 where python:

C:\Users\xxx\Anaconda3\python.exe
C:\Users\xxx\AppData\Local\Microsoft\WindowsApps\python.exe

Answer 1

转到 anaconda cmd 或 miniconda cmd 并输入这个

conda install -c anaconda scikit-learn

之后重启 spyder 或 pycharm

Answer 2

您的 jupyter 似乎使用了名为 tf_plates 的环境，但 scikit-learn 安装在 base 环境中。你可以

在此环境中安装scikit-learn：

conda install --name tf_plates scikit-learn

另一种选择是在 jupyter 中使用 base 环境：

在您的 kernel.json 文件中将 C:\Users\33826\Anaconda3\envs\tf_plates\python.exe 更改为 C:\Users\33826\Anaconda3\python.exe
