InvalidOperationException：序列化Synapse类型的对象时检测到循环引用

Question

我正在尝试保存培训数据

public void saveNetwork()
{
    var serializer = new XmlSerializer (OutputLayer.GetType());
    var stream = new FileStream ("Assets/Dataset.xml", FileMode.CreateNew);
    serializer.Serialize (stream, OutputLayer);
    stream.Close ();
}
