Hi, In This

Hi,
in this https://allegro.ai/blog/accelerate-hyperparameter-optimization-with-pytorchs-ecosystem-tools/ you mention PBT as a possible hyperparameter tuning/technique/scheduler. Does trains support PBT? I am asking because looking at Optuna's API, it https://github.com/optuna/optuna/issues/287#issuecomment-450269160 that they do not support PBT.

Do you have a specific PBT implementation you are considering ?

Yes. Ray has a nice implementation of that and of many other things (It also supports Optuna & BOHB internally). This could relate to a https://github.com/allegroai/trains/issues/227#issuecomment-716513710 I opened in the GIT.

TPE and HBOB are competitive to PBT in terms of performance

Yes, and I believe ASHA is also, but I wanted to compare PBT.

Thanks anyway.

Hi OddAlligator72

it 

 that they do not support PBT.

The optimization algorithm themselves are usually external (although the trivial stuff are in within Trains)
