I got the same question.

I got the same question.

Friend, have you resolved the issue? I feel like the downloaded data for the validation set might not correspond to the correct version.

Yeah, I just set all the batchsize to 1 and it works. Probably because it use only 1 GPU during the eval phase. Following the dataset.md, I didn't have any problem in preparing data.

Thanks your patient reply extremely，Can you give me your train command as a reference, because I am using 4 GPU devices and I also want to switch to training with one GPU like yours，Furthermore, which version of the PascalVOC dataset file, dataset.md, did you choose to download? I am using VOCtrainvalue_ In 2007, my error also appeared in the PascalVOC folder. The len (batched_inputs) of a single PNG image under JPEGImages was 2

[MaureenZOU]

Evaluation with 1-gpu is because if we concatenate images in a single batch, e.g. one image with [512, 1024], another image with [1024, 512], the concatenated batch would be [2, 1024, 1024], padding so much zero will largely influence the performance.

1. If you want to download pascalVOC, please download the 2012 version from website: http://host.robots.ox.ac.uk/pascal/VOC/
2. For the VOC len(batch_size) problem, please change the config e.g.

   Segment-Everything-Everywhere-All-At-Once/configs/seem/focalt_unicl_lang_v1.yaml

   Line 330 in 7b2e76d

   BATCH_SIZE_TOTAL: 8

   , you can add VOC.TEST.BATCH_SIZE_TOTAL 1 in the command

Thank you for your patient answer.If I have 4 GPU devices, should I use VOC TEST BATCH_ SIZE_ Total set to 4？

Yes, exactly, that is how many total test size, and on each gpu it would automatically load len(batch) = BATCH_SIZE_TOTAL/NUM_GPUS
