It is a reference to a literary image from ancient Greek and Latin literature, first found in the Odyssey, where dream spirits (Oneiroi, singular Oneiros) are divided between those who deceive dreamers with false visions, who arrive to Earth through a gate of ivory, and those who announce a future that will come to pass, who 为什么取名为 Keras? Keras (κέρας) 在希腊语中意为 号角 。 它来自古希腊和拉丁文学中的一个文学形象，首先出现于 《奥德赛》 中， 梦神 (Oneiroi, singular Oneiros) 从这两类人中分离出来：那些用虚幻的景象欺骗人类，通过象牙之门抵达地球之人，以及那些宣告未来即将到来，通过号角之门抵达之人。 Keras: La librairie de Deep Learning Python.
