About iw3 update process issue

[laiyangli001]

Why everytime to run update.bat,models need to be downloaded again,even there is no change of models file

[nagadomi]

It’s not actually downloading the model file.(checkpoint/weight/parameter file).
It reloads the source code for each model from its own separate repository.
