Did you run python download_data.py --kitti_url URL_YOU_RETRIEVED? This should download and prepare all data.

yeah I used python download_data.py --kitti_url URL_YOU_RETRIEVED to retrieve data. And it said all done. the problem showed up when try to use train.py. And I tracked the error line to KittiSeg.json found the URL is empty.

This message comes, when no folder data_road cannot be found. Can you check whether there is a folder data_road in RUNS or $TV_DIR_RUNS?

my data_road is in MultiNet/DATA, is it supposed to be in RUNS/?

No, sry it should be in DATA. Is there a dir data_road?

yep. there is.

And I after I put the URL manually, new error occurred:

It seems the URL is not readable?

The code tries to download the data in kitti_seg_input. All files seams to be there. The routine should be skipped at this : line
Can you check, why if os.path.exists(vgg_weights) and os.path.exists(kitti_road_dir) returns false? Is data_dir set correctly?

Hi, I think I found the issue. Can you try using commit c1612e3 and run training again?

Can you checkout the unmodified hype? It should work without setting the kitti_url.
The quoted issue indicates that your hype does not follow the .json specification (Forgot using quotes when pasting the kitti url?).

yeah that error fixed! but another one showed up.. lol

And it happened after running several layers.

This looks as if you are using an old version of KittiSeg. Try updating all submodules by running:
git pull
git submodule update --recursive

yeah fixed after review #10. One question, it asked like this:
ERROR File '/home/ubuntu/didicompetetion/Hao/MultiNet/hypes/../DATA/weights/vgg16.npy' not found. Download it from ftp://mi.eng.cam.ac.uk/pub/mttt2/models/vgg16.npy
ERROR File '/home/ubuntu/didicompetetion/Hao/MultiNet/hypes/../DATA/vgg16.npy' not found. Download it from ftp://mi.eng.cam.ac.uk/pub/mttt2/models/vgg16.npy
So I just put vgg16.npy both in DATA/ and DATA/weights/, that makes me confused.

commented on July 17, 2024
Yeah, the different submodules read the data from different location. Should properly fix this. For now you can avoid downloading it twice by creating a symlink ln -s weights/vgg16.npy vgg16.npy or vice versa.
