Cannot upload annotations (YOLO 1.1 format)

[cait-newport]

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

I created a new project and a task and uploaded images I want to label (bounding box). When I try to upload annotations, I get the following error:

"Could not upload annotation for the cvat.apps.dataset_manager.bindings.CvatDatasetNotFoundError: Check format docs. Dataset must contain a file: "obj.data"

I thought the issue was with the paths for the labels and images. I tried making a new project, uploading 10 images, annotating them, and exporting the results. I then copied the folder paths exactly as they were in the exported folder (e.g. project_name/obj_train_data/image_0000.txt). Within the project_name folder, there are files called obj.data, obj.names, train.txt. I have then compressed the project_name folder and tried to upload that.

I have tried many variations on this (e.g. different folder paths, adding a dataset.yaml, including the images folder when I upload the annotations) but I always get the same error. I have included a log of the error.

I am also including the zip file I used to upload the annotations.

testing.zip

cvat_error_log.txt

Expected Behavior

No response

Possible Solution

No response

Context

Dataset size: 8786 images
The dataset has already been annotated but I know there are errors in some of the bounding boxes. I am not sure if these errors (e.g. negative numbers) would cause the issues, but I can view those images and bounding boxes when matplotlib.

Environment

OS: MacOS Sonoma 14.7
Browser: Google Chrome
CVAT Server version: 2.23.2
CVAT UI version: 1.67.0

If to extract your archive on Linux (WSL), I may see it has the following structure:

__MACOSX/
    testing/
        /._obj.data
        /._obj.names
        /._train.txt
        /obj_train_data/

Unzipping on Mac extracting correct structure. So, this is Mac only related issue.
Anyway, I believe we should add support for such mac os created archives in CVAT.
