I use GFnet to train my own dataset, and the performance of the RV branch is very low. I canceled all data augmentation operations. The miou of RV is only about 10, have you ever encountered this problem?
How much memory is needed for inference with nuscenes? I have 70G of free memory, but I found that the memory was fully occupied and the system hanged. What caused the excessive memory usage? I didn't have this problem during training.
Hi. Thanks for your open source work. I have some ques about details.
Look like you only use trans Data Aug in Train. And look like the data aug code is similar with salsanext.
As far as I know, kprnet's special unfolding projection method, also called proj_version='v2' in your code, causes out-of-bounds errors when using data aug, which I think is the reason why you only use one type of aug.
However, in my past experiments, errors occurred even when using only similar trans Data Aug.
So I want to know, did the data augmentation work fine in your experiment?

Have you studied the effect of different choices of K by KNN in kpconv? Your implementation chooses the same 7 as KPRNet, and I'm wondering if this affects performance.

Hi @haibo-qiu, thank you for open-sourcing your work!
Regarding the experimental results of GFNet, could you share with me what score you got on the val set of nuScenes? Thanks!
can u push it on dockerhub? QAQ
Hi, thanks for your great work and share the code!
When I try to reproduce your result, the error occurs because the knn fiiles don't exist. I would like to know how to generate knn files.
