Hi Transformers team,

While using the Florence-2-base-ft model through HuggingFace Transformers, I encountered the following Python warning:

SyntaxWarning: invalid escape sequence '\d'
C:\Users[USER].cache\huggingface\modules\transformers_modules\Florence-2-base-ft\processing_florence2.py:515

This comes from the following code in processing_florence2.py:
PATTERN: 'r<time_(\d+)><time_(\d+)>([a-zA-Z0-9 ]+)'

The issue is that the regex pattern is written as a regular string instead of a raw string, causing Python to interpret \d as an invalid escape sequence.

Suggested fix:
Change this:
PATTERN: 'r<time_(\d+)><time_(\d+)>([a-zA-Z0-9 ]+)'

To this:
PATTERN: r'<time_(\d+)><time_(\d+)>([a-zA-Z0-9 ]+)'

This will avoid the SyntaxWarning during runtime.

Thank you for maintaining this library and for the Florence-2 integration!

Hi @hookylee, thank you for the feedback! The Florence-2 code is currently being ported into the main Transformers library, and I've added this as a suggestion.
