**what exactly the resolution parameter does? if i apply resolution=320, does it means that images are resized for training model to 320x320?  
i’d like to keep size of my images unchanged, even if it takes longer to do the training**

Are you creating a dataset version with Roboflow? If you have a preprocessing step for resizing, the image can adjust its size according to the rule you set (stretch to, fit, fill etc.)

If you don’t want any resizing, you can just remove the preprocessing step entirely!

no, i talk about the model itself, if you want to run it yourself, not via robolfow web app.  
Got an answer trom the development team i’ll post it here for others who might have same question :  
We (RF-Detr) train using multi resolution but the resolutions at what we train are resolved using provided input resolutions.
