How severe does this issue affect your experience of using Ray?
- Medium: It contributes to significant difficulty to complete my task, but I can work around it.
Pickling of native torch model fails when saving for a ray.rllib.algorithms.* model implementation.
RLLIB error message: “”“Could not save torch model under self[TorchPolicy].model!
This is most likely due to the fact that you are using an Algorithm that
uses a Catalog-generated TorchModelV2 subclass, which is torch.save() cannot pickle.
What is the recommended way of saving a native torch model for e.g. ray.rllib.algorithms.dqn.dqn_torch_model, which is not implemented under ray.rllib.models.* ?
