    Detected Cython version 0.27.1
      This version of Cython is untested with Kivy. While this version may
      work perfectly fine, it is possible that you may experience issues. If
      you do have issues, please downgrade to a supported version. It is
      best to use the newest supported version, 0.25.2, but the minimum
      supported version is 0.23.
    
      If your platform provides a Cython package, check if you can downgrade
      to a supported version. Otherwise, uninstall the platform package and
      install Cython via pip:
    
        pip install -I Cython==0.25.2
    User distribution detected, avoid portable command.
