For historical reasons, We keep "no name" models here, which are different from "specified name" models.

NOTE: Training the models in legacy folder will generate models without specified parameters.

• Released models: not specify parameter names

model	top-1/top-5 accuracy(PIL)	top-1/top-5 accuracy(CV2)

SE_ResNeXt50_32x4d	78.32%/93.96%	77.58%/93.73%
