Transformer trackers pretrained weights

Hi, I am developing a transformer-based object detector and tracker from scratch. For the tracker component, I am working off of trackformer and/or MOTR for now. My problem is that I currently don’t have access to a strong GPU to training. Does Huggingface have pretrained weights on the coco dataset and a resnet50 backbone that I can use for prototyping before I find a cost-effective way of accessing a GPU?
