Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/64557
MaskRCNN speed depends on how many people detected in the detection stage. A random input from dataloader doesn't satisfy this. In order to standardize the benchmarking, we use 2 standard image for benchmarking, 2/3 people.
