Question on Mapillary pretrain when evaluating on cityscapes(val) dataset

[littleSunlxy]

I met a problem when training on Mapillary and evaluating on cityscapes. The class "wall" miou=0.0.
Could you please provide the training log of Mapillary pretrain and eval？(prefer Model B2) Thanks a lot!

Hi
Sorry, I didn't try pre-train MV using B2 model, and I didn't have results about eval on cityscapes.
I only pre-train SegFormer-B5 on MV and finetune on cityscapes. I didn't look at the detail of MV train-> City eval

[littleSunlxy]

Oh,I see. I hope to see more details of MV pre-trained -> City finetune, Do you have the log of SegFormer-B5? Thanks!

[xieenze]

No, we didn't organize this part of code and config, so currently we cannot provide it. We consider to public it in the future. (Recently I am busy on other projects)

But it is super easy to pre-train on MV-> finetune on city, if there are some detail make you confuse, you can contact me and I will try to figure it out.
