--year 2012_aug

[ynjiun]

Hi VainF,

I am able to train --year 2012 with following command:

python main.py --model deeplabv3plus_mobilenet --enable_vis --vis_port 28333 --gpu_id 0 --year 2012 --crop_val --lr 0.01 --crop_size 513 --batch_size 14 --output_stride 16 --continue_training

But when I try to train --year 2012_aug, I encounter following error:

FileNotFoundError: [Errno 2] No such file or directory: './datasets/data/VOCdevkit/VOC2012/SegmentationClassAug/2008_002913.png'

In my ./datasets/data/VOCdevkit/VOC2012/SegmentationClassAug directory, I have train_aug.txt file in it. What am I missing? Please help. Thanks a lot.

P.S. I did check 2008_002913.png exists under ./datasets/data/VOCdevkit/VOC2012/JPEGImages
So do I need to copy all the .png files to ./datasets/data/VOCdevkit/VOC2012/SegmentationClassAug? or what should I do to fix this problem? Thanks for your help.

Edited: after follow the instruction to download labels from the dropbox and extract to ./datasets/data/VOCdevkit/VOC2012/SegmentationClassAug then every thing works as expected.

Hello @ynjiun ! I am facing an issue somewhat related to your issue. I unzipped the SegmentationClassAug.zip file from the dropbox. In the folder I am able to see the images, but the train_aug.txt file is missing. Can you please share this text file with me?
