ray.rllib.core.rl_module.multi_rl_module.MultiRLModuleSpec.build

MultiRLModuleSpec.build(module_id: str | None = None) → RLModule

Builds either the multi-agent module or the single-agent module.

If module_id is None, it builds the multi-agent module. Otherwise, it builds the single-agent module with the given module_id.

Note: If when build is called the module_specs is not a dictionary, it will raise an error, since it should have been updated by the caller to inform us about the module_ids.

Parameters:

module_id – Optional ModuleID of a single RLModule to be built. If None (default), builds the MultiRLModule.

Returns:

The built RLModule if module_id is provided, otherwise the built MultiRLModule.
