How to finetune Osprey on RefCOCOg?

[Glupayy]

Hi! Thanks for the great work!

Could you share any configs on fine-tuning Osprey on RefCOCOg dataset? I am trying to follow your work and reproduce the results on it, what's the starting checkpoint and the prompt template? It would be very appreciated if any fine-tuning config could be shared. Thank you!

Hi, @Glupapa The starting checkpoint is our final model Osprey-7b, and the prompt template is the same as RefCOCO as in https://github.com/CircleRadon/Osprey/blob/ca9f26dbd9a0907d8ff686588a394fa897b60828/osprey/datasets/stage2_data.py#L256C26-L262C1 The config is as follows,
