How to resume training after 2 billions steps?

Unity Engine

Hi.
I’m trying to train my 2d ragdoll character to take the right position on 14 points - 1 for each bone.
I use PPO and can see my entropy slowly goes down from 1.5 to 0.26 until now.

Here i’ve met some problem: when training reached 2147400000+ step - it stopped with NaN relative exceptions. So when i’m trying to resume the training - it’s just starts from: -2147483625 step (from negative step) and immediately stops.

So i need help about how to resume training after 2 billions steps? Is that the limit?

Maybe start a new training run using –initialize-from
Haven’t tried this myself yet, but from what I’ve read in the docs, it sounds like that could be a workaround for your issue.

3

Already tried. And even –initialize-from from other training which was started with –initialize-from from origin 2 bills train - the same exception result**.** It feels like some int var is stored inside origin brain.

4

Can you share the full stack trace/log containing the exceptions?

5

Here is first exceptions and secondary after resume

First exception when steps count became too large
