使用2个1080ti的情况下
只有调整batch_size=4
input size=378*378
才不会出现这个问题。。
但是效果就不好

我就用了4个1080ti，把batchsize设置成8 但是效果还是比作者batchsize=16的模型差了约2%
顺便问一下你调整reference frame和使用crf结果会有差距吗？我测试的结果没有差距 很奇怪

能加个qq交流一下吗，我猜是因为你的4路1080ti的问题。作者应该是用了两个24gram的Titan，因为你这样训练相当于每个GPU上只有两个在做BN，一般至少四个。没看见作者代码里写了跨GPU的BN。而且1080ti的图片size必须得限制到378以下。我的qq是2667004002
