mAP on new images using trained model

[ShriMLEngineer]

Hi,

I have trained DETR on 3000 train and 600 val images and I am getting mAP more than 80%. All good till here.

Now, I have got new dataset of 100 images and I want to use my model to create mAP on these 100 images without changing my model.
Please advise how to do it?
