loss:Nan #3
Comments
loss刚开始在8-11之间跳动之后一直是nan;该怎么解决呢 |
我的代码没有将正例周围的点忽略,所以需要用梯度裁剪,你可以把clip_grad的值调低一点。 |
你现在解决了吗? |

新年好!
抱歉新年来打扰您。我目前在跑EDVR这个模型、能成功的用自己的数据训练并且得出看着不错的效果。我这里有几个疑问就是:1.这个模型需要用大量的数据(2.8T)来训练吗?2.预测出来的图片有什么评估指标吗?

评估指标可以用MSCOCO数据集提供的api,在我的run_cocoeval.py里有,需要按照它的数据格式组织。如果你需要一个粗略的测评方法,可以参照fcos/utils_box/eval_csv.py,使用VOC的测评方法。 |
