LostAndFoundDataset

Hi @adynathos

For the LostAndFoundDataset from http://www.6d-vision.com/lostandfounddataset, what are the packages that we should download?

Also is the downscaled version of cityscapes available? DIR_CITYSCAPES = Path(os.environ.get('DIR_CITYSCAPES', DIR_DSETS / 'dataset_Cityscapes' / '2048x1024')) DIR_CITYSCAPES_SMALL = Path(os.environ.get('DIR_CITYSCAPES_SMALL', DIR_DSETS / 'dataset_Cityscapes' / '1024x512'))

Hello, We download the images (leftImg8bit) and labels (gtCoarse), then resize them with a script. Please see the description here

I end up with the following error:

I do have Libwebp and Imagemagick installed.

Hi @adynathos ,

I was able to overcome the previous error by adding the following in compress_images.py:

import asyncio, sys if sys.platform == 'win32': loop = asyncio.ProactorEventLoop() asyncio.set_event_loop(loop)

However i was able to downsample only the leftImg8bit images and not the gtCoarse images. I got the following error for all the images:

--Stderr-- b'Invalid Parameter - -filter\r\n' --Stdout-- b''

Replacing "convert" to "magick" (line 17) in the sh files fixes the issue.

Thank you for finding that. I did not run the software on Windows and was not aware of the problem. I added your fixes here 4035478c3548563e1c4ca38e716b23b33d5daa6e
