Description
Propagate
*argsand**kwargsto TransformedEnv'sstate_dict.Motivation and Context
Since TorchRL's environments are
nn.Module, they contain astate_dict. However, the TransformedEnv 'sstate_dictclass does not accept any*argsor*kwargs. This PR fixes that.Example: I implemented an example notebook of PyTorch Lightning + TorchRL based on the pendulum tutorial with the
LightningModulecontaining bothenvandpolicy. The following error is raised:which happens because of the
TransformedEnvclass. With the simple change of this PR this does not happen anymore.Types of changes
