Hi everyone,  
I was playing with Dinov2 model of the transformers library of HF and I have a question.  
If I change the image\_size in the config.json file, than this will change the real input image size of the model or will be changed after by the parameters of the preprocessor\_config.json?  
I tried training a model here :

> **[lombardata/dino-large-2023\_12\_08-with\_custom\_head-imgsize1036 · Hugging Face](https://huggingface.co/lombardata/dino-large-2023_12_08-with_custom_head-imgsize1036)**
>
> We’re on a journey to advance and democratize artificial intelligence through open source and open science.

and I changed the input image size (from 518 to 1036). But then I saw that the “crop\_size” parameter in the preprocessing file is still: {“height”: 224,“width”: 224}. Is useless to change img size if the crop\_size is unchanged?  
What would be the best practice in order to fill the entire image to the model?  
Thank you all in advance !
