受不了，我还特地配置了c的环境变量，还是不能成功配置sklearn

Answer 1

这个错误是在安装sklearn时错写了错误。 numpy: markers 'python_version == "3.10" and platform_system == "Windows" and platform_python_implementation != "PyPy"' don't match your environmen 这里提示了numpy 当前的版本和python3.10不匹配。
解决方法是，可以安装较低版本的numpy看看，比如，pip install numpy==1.19.2 或其他版本
