How to prolong training after 1000 without starting from 0 ?

[eziolanza]

Hello,
simple question. I have trained my dataset 2d -f all with standard trainer up to 1000 epochs. I think there's more to learn, hence I would like to prolong to 2000 epochs.
Do I have to start from 0 or there's a way to continue from where I left, even though I'm gonna be using a different trainer?

Thanks
