I can't export image in version 1.19

Describe the bug
After I upgraded the version of label-studio from 1.15 to 1.19, the image folder was empty when exporting the dataset in YOLO format.

To Reproduce
Steps to reproduce the behavior:

1. Set Cloud Storage to Local files
2. Label theimages
3. Select YOLO with Images when exporting
4. The images folder in the zip file is empty

Expected behavior
In version 1.15, it can correctly export zip files containing images.

Hello,

Can you try these steps please and let us know if it works:

1. Select the YOLO with Images format (not plain YOLO).

Ensure Label Studio can serve your local files. In a local (on-prem or Docker) install that means setting these environment variables before you start Label Studio:

export LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED=trueexport LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT=/absolute/path/to/your/images

3. Restart Label Studio so those vars take effect.
   Once LS can reach your image folder via /data/local-files, the YOLO with Images export will populate the images/ directory again—just as in v1.15.
   If you prefer a command-line approach, you can also run:

   label-studio export <PROJECT_ID> YOLO_WITH_IMAGES --export-path=/tmp/your_export

Thank you,
Abu

I tried following your method, but it didn't work.

I attempted to use Docker to create a Label Studio instance, but the exported ZIP file still does not include the images.

Here are the steps to reproduce the issue:

1.Create a Docker container:

docker run -it -p 8080:8080 -v $(pwd)/mydata:/label-studio/data \
--env LABEL_STUDIO_LOCAL_FILES_SERVING_ENABLED=true \ 
--env LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT=/label-studio/files \ 
-v $(pwd)/myfiles:/label-studio/files \
heartexlabs/label-studio:latest label-studio

2.Log in and create an Object Detection project:

3.Set up local storage:

4.Annotate the files:

5.Export in "YOLO" format with the "YOLO with Images" option checked:

I have also tried running label-studio export 1 YOLO_WITH_IMAGES --export-path=/label-studio/files/ inside the container, but there were no images in the output either.

Hello,

Can you make sure the LABEL_STUDIO_LOCAL_FILES_DOCUMENT_ROOT is absolute? I do see in the the storage is /label-studio/files/data1 that might cause some issue. Can you please also check if there are any logs in the LS that show any error?

Thank you,
Abu

Hello,

I have the same issue for export local storage files. And I track down to the label-studio-sdk, found codes below.
Well, I think that can explain the bug: for local storage file it just return the path without copy to the cache_dir(unlike the uploaded file, which it does).

https://github.com/HumanSignal/label-studio-sdk/blob/3a730763fc180169eaa9c4ac663a6cf7288bcad9/src/label_studio_sdk/_extensions/label_studio_tools/core/utils/io.py#L123

I create a PR for that:
HumanSignal/label-studio-sdk#494

Below these will work for me @Ku-yuan :

1. copy label_studio_sdk to host sudo docker cp label-studio:/label-studio/.venv/lib/python3.12/site-packages/label_studio_sdk ./
2. Add two lines above in the PR.
3. Rerun the docker with directory mount:

sudo docker run -id --name label-studio \
    ... \
    -v ./label_studio_sdk:/label-studio/.venv/lib/python3.12/site-packages/label_studio_sdk \
    heartexlabs/label-studio:latest label-studio

4. Finally export.
