How to train a 132MB MViTv2-small model

[gzwo-O]

The ckpt of the MViTv2-small model I downloaded from the MMlab project is only 132MB（link）, but the checkpoint size saved by the model trained with the project's code is 396MB (I checked my config file and the config file of the 132MB model and found no difference), and the checkpoint size I trained with the code from the SlowFast repository is also 396MB. How can I train a 132MB model?
