Hi @felixdittrich92 , my apology it took me a while to actually work on it, I've been dealing with some issues from work.

I've got some questions about the URLs for download, COCO-text has 2 separate URLs, the first one is for the images, and the second is for the labels, but the VisionDataset only accepts 1 URL which I believe lead to a compressed images and it's labels.

I also checked the other datasets (funsd, cord, synttext, etc), and all of them initialized the VisionDataset using 1 URL only, I was thinking about merging the files myself, but then I was wondering if that's the right thing to do. (Changing the base class should not be an option I believe)

Sorry, and thanks in advance. :)

Hi @dvando 😄
No stress ^^

Option 1: You could take a look at https://github.com/mindee/doctr/blob/main/doctr/datasets/imgur5k.py (here the user needs to provide the paths to the data and we provide only the loader)
Option 2: What's the dataset size in MB / GB ? What's the license ? If both isn't troublesome we could combine the dataset and upload it :)

So with option 1, the user should download the images and the labels by themself? That sounds okay.
The dataset has ~13 GB in size and has CC by 4.0 license.

Both sound fine to me, which one do you prefer @felixdittrich92 ? :)
