你好 请问你写出来了吗 我用楼下的方法 跑出来只能达到59 也用了预训练模型 请问你尝试过了吗 想请教一下

请问能分享一下吗? 不知道如何写dataset和dataloader。感谢

我就跑了一遍,电脑太拉垮了,我刚跑78/100epoch,现在miou是50.4 为什么要追求高miou?50已经很不错了吧。够用不就可以了吗?

看别人都是用70多,他们的代码又运行不动。不好做对比,有点难受

@minshengxinwen 您好老哥,请问有进展了,我也是这样的miou,不知道该怎么修改

是我大意了,我没怎么看过语义分割的论文,刚搜了一下,50多确实不高。你可以尝试这几种方法:1、更改网络的主干模型,也就是特征提取模型,换一个复杂点的。 2、增加数据集,源代码只用到了train的数据,你可以把val的数据也加进去,然后再利用那个文件生成train.txt与val.txt。 不是还有非精细分割的20000张图片,尝试通过数据量提上去。

谢谢老哥的回复,最近我已经尝试将cityscapes数据集上训练该网络,就是miou一直上不去,不知道什么原因,实在想不通自己哪里不对劲,我再试试把,谢谢老哥的答复
