Description
llama
模型上测试的效果,此时我设定的pp_degree=4
,vpp_degree=2
,acc_step=4
:当hidden_layer=8时,vpp编排的结果如下:
当hidden_layer=7时,vpp编排的结果如下:
因为vpp编排是根据chunk进行编排的,所以在两个参数下,编排的效果是一致的,这也证明了代码的准确性和通用性
当hidden_layer=8时,训练后的结果如下:
当hidden_layer=8时,训练后的结果如下:
可以看到,此时loss相差0.007,但是时间上相差了0.005*10=0.05s。而这仅仅是训练的step为10,并且hidden_layer较小时的结果,可以预期,当模型较大,训练步数较大时,带来的时间收益是非常显著的。
