Namespace Error when trying to train reward model

[bhauptvogel]

I ran python trainer_rm.py --configs defaults_rm oasst-rm-1-pythia-1.4b inside the model/model_training folder.

I got an error trying to train the model:

python trainer_rm.py --configs defaults_rm oasst-rm-1-pythia-1.4b

You are using a model of type gpt_neox to instantiate a model of type gpt_neox_reward_model. This is not supported for all configurations of models and can yield errors.
Some weights of GPTNeoXRewardModel were not initialized from the model checkpoint at andreaskoepf/pythia-1.4b-gpt4all-pretrain and are newly initialized: ['out_proj.bias', 'out_proj.weight']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.
Number of trainable parameters: 1311M

AttributeError: 'Namespace' object has no attribute 'residual_dropout_lima'. Did you mean: 'residual_dropout'?

It worked (I didn't get the error when I added residual_dropout_lima: true to the config.yaml. (But I don't know if it is supposed to be true or what it does in general)
The following attributes are missing from the Namespace:

• residual_dropout_lima
• use_system_tag
• system_property_dropout
• system_add_length

I only tried the oasst-rm-1-pythia-1.4b model, the other model sizes have to be tested.
