Which pre-trained model is used for training?

Which model you used for training? Is it ssd mobilenet v1 coco with input size 300x300?

I think you had trained with input image size 512x512 right? I am also trying to train mobilenet V2 coco with input image size 512x512, but there seems to be no changes as compared to 300x300. How can I do that? I am using per-trained weights from Tensorflow zoo for fine-tuning.
