How many parameters does Swin-Transformer-V2-giant have?

[wusheng816]

I made the following modifications in 'configs/simmim/simmim_pretrain__swin_base__img192_window6__800ep.yaml', and trained a model with 2.6 billion parameters, which is 400 million less than swin-V2-giant claimed 3 billion. I wonder how many parameters does the official version of swin-V2-giant have? Thanks!
