Adjusting values in default config file?

Flatland
#1

I wanted to try some of these models:

It tells me i don’t have the required resources available for some of them and tells me i can set num_workers, num_gpu in the default config file, but i can’t find any such file. Is this repo unfinished and i’m digging too soon into it?

Pretty much yes :wink:

But you are free to start experimenting with it anyway! The basic idea is that you point train.py to an experiment file.

So in the following example: python ./train.py -f experiments/flatland_random_sparse_small/global_obs_conv_net/ppo.yaml

you are using this file: https://gitlab.aicrowd.com/flatland/neurips2020-flatland-baselines/blob/master/experiments/flatland_random_sparse_small/global_obs_conv_net/ppo.yaml

In there you have num_gpus: 1 and num_workers: 7 so to run that you’ll need at least a GPU and at least 8 cores (7 workers + 1 main thread). Just tweak these values to match your hardware!

But yeah this is still mostly undocumented and very experimental so expect rough edges :skull_and_crossbones::zap:
