I've encountered a lora (now deleted) that has layers diffusion_model.blocks.0.mlp.down.alpha/lora_down.weight/lora_up.weight. Checking the last two parts causes mlp.down.alpha to be detected as a down layer (instead of lora_down.weight as intended), which then crashes in
old_rank = lora_down_weight.size()[0].Double checking the lack of .alpha key corrected this error and should have no downside since alpha is assumed to be reserved in another place.
Edit: Have encountered another one since by someone else.
