代码报错：ModuleNotFoundError: No module named ‘sklearn’
原因是缺少sklearn库导致的，需要安装，但是如果你直接
pip install sklearn 会报错：
× python setup.py egg_info did not run successfully.
│ exit code: 1

The ‘sklearn’ PyPI package is deprecated, use ‘scikit-learn’
rather than ‘sklearn’ for pip commands.
Here is how to fix this error in the main use cases:
– use ‘pip install scikit-learn’ rather than ‘pip install sklearn’
– replace ‘sklearn’ by ‘scikit-learn’ in your pip requirements files
(requirements.txt, setup.py, setup.cfg, Pipfile, etc …)
– if the ‘sklearn’ package is used by one of your dependencies,
it would be great if you take some time to track which package uses
‘sklearn’ instead of ‘scikit-learn’ and report it to their issue tracker
– as a last resort, set the environment variable
SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True to avoid this error

note: This error originates from a subprocess, and is likely not a problem with pip.

实际上解决办法是：
pip install scikit-learn
或者在conda环境下输入：
conda install scikit-learn
