Why model storage memory takes a huge amount of space?

Hi,

I see your saved models for imageNet are very huge (48.2MB) while in the code they are 4.9MB (#parameters). I also double checked MobileNet v2 only 14.02MB on Pytorch.

Could you explain why your model is very huge? It should be small in memory storage.

Personally, 4.9M means the number of 4.9 million learnable parameters rather than storage.

Thanks for your information.

Do you know why the models in pytorch are very huge (48.2MB)? I see same scale models (Mobilenet v1, v2) with 4.4M and 3.9M (#parameters) only take little space (14.02MB or 16MB).
