is there a guide regarding the configuration required for dockers?

Yes we do have a guide: https://github.com/allegroai/trains-agent#starting-the-trains-agent-in-docker-mode

You can also specified the image for the docker, in the example the image is nvidia/cuda but you can put a specific one for your needs (maybe nvidia/cuda:10.1-runtime-ubuntu18.04 ?

I can give it a shot (I’m using conda now) what is the overhead of going into dockers with the fact that I dont have “docker hands on experience”?

You don’t really need “docker hands on experience”

is the flow using dockers is more supported than conda?

Its the same flow, but running inside a docker image
