Question:

I get this error whenever I try and export my labels as yolo format. VOC format works fine.

Traceback (most recent call last):

Answer:

This error happens when the file already exists in the temporary directory. To resolve it, please do one of the following:

  • Clear your /tmp directory.
  • Ensure that the /tmp directory is writable.

Doing so should remove any existing conflicts when attempting to export the labels in YOLO format from Label Studio.
