I tried to reproduce the results mentioned on this model card. The received mAP does not match the claimed mAP in the model card.

• Claimed mAP: 43.5
• Recieved mAP: 40.9

Here are the details for my validation:

• I instantiate pre-trained model with transformers.pipeline() and use COCO API to calculate AP from detection bboxes.
• Evaluation was performed on macOS CPU.
• Dataset was downloaded from cocodataset.org

 Average Precision  (AP) @[ IoU=0.50:0.95 | area=   all | maxDets=100 ] = 0.409
