This is out of schedule release with a bugfix that was introduced in version 1.4.5
In version 1.4.5 there was a bug that went unnoticed - if you used pipeline that consisted only of ImageOnly transforms but pass bounding boxes into it, you would get an error.
If you had in such pipeline at least one non ImageOnly transform, say HorizontalFlip or Crop, everything would work as expected.
We fixed the issue and added tests to be sure that it will not happen in the future.
