How to fix the following errors?

[missflash]

The following error occurred while running cell 10 in 6. Tune language model using PPO with our preference model.
After adding __init__.py to /content/trlx/examples/summarize_rlhf/reward_model/, I still get the same error.
How can I fix it?

     10 import torch
     11 from datasets import load_dataset
---> 12 from reward_model.reward_model import GPTRewardModel
     13 from tqdm import tqdm
     14 from transformers import AutoTokenizer

ModuleNotFoundError: No module named 'reward_model.reward_model'; 'reward_model' is not a package
