Why Swin-Large-W12 contains [36, 36] encoder.layers.3.blocks.0.attn.relative_position_index #30

Original Swin-Large and the current code seem to have same window_size across layers, and if their window_size set to be 12, then the shape of all relative_position_index should be [144, 144].

But I found that the provided checkpoint has [36, 36] for encoder.layers.3.blocks.0.attn.relative_position_index.

Am I missing something?
