patch_embed related questions.

Hi, Thanks for providing the code! I have a couple of questions regarding patch_embedding.

1. in https://github.com/whai362/PVT/blob/v2/segmentation/pvt.py#L148, the last layer you added one more embed feature than the num_patches but it seems this extra feature has no where to be used. You explicitly removed it in https://github.com/whai362/PVT/blob/v2/segmentation/pvt.py#L202. Is this design for some specific purpose? (backward compatibility?)
2. https://github.com/whai362/PVT/blob/v2/segmentation/pvt.py#L183 why specifically compare with patch_embed1? Is this not supposed to compare to each patch_embed?

I have the same confusion about your questions. Did you solve them?
