Combined Observation

Combined Observation¶
TL;DR
This observation allows to combine multiple observation by specifying them in the config file.
💡 The idea¶
Provide a simple way to combine multiple observations.
🗂️ Files and usage¶
The observation is defined in neurips2020-flatland-baselines/blob/master/envs/flatland/observations/combined_obs.py.
To combine multiple observations, instead of directly putting the observation settings under observation_config, use the names of the observations you want to combine as keys to provide the corresponding observation configs (see example).
An example config is located in neurips2020-flatland-baselines/baselines/combined_tree_local_conflict_obs/sparse_small_apex_maxdepth2_spmaxdepth30.yaml and can be run with
Run it with:
$ python ./train.py -f baselines/combined_tree_local_conflict_obs/sparse_small_apex_maxdepth2_spmaxdepth30.yaml
📦 Implementation Details¶
This observation does not generate itself any information for the agent but just naively concatenates the outputs of the specified observations.
📈 Results¶
Since this observations is meant as a helper to easily explore combinations of observations, there is no meaningful baseline. However, we did a run combining tree and local conflict observations as a sanity check:
