A problem about scikit-garden

[Urazome2021]

When I install scikit-garden, it keeps prompting me that the installation has failed, does anyone have the same problem? If solved, can you share the solution?

You need to meet the installation conditions of scikit-garden. Check whether you meet the following conditions：
{
install_requires=["numpy", "scipy", "scikit-learn>=0.22", "six"],
setup_requires=["Cython>=0.23", "numpy", "setuptools>=18"],
setup_requires=["Cython>=0.23,<3.0", "numpy", "setuptools>=18"],
}

especially "Cython>=0.23,<3.0"
