"Error Encountered While Running data_analysis.py Script: Missing Attribute in AutoBotDataset"

[jayahn77777]

Thanks to your help, I was able to successfully run the training and evaluation processes. However, when I ran the python data_analysis.py script, I encountered the following error:

(unitraj) D:\Coding\Python\nuScenes\unitraj\UniTraj\unitraj>python data_analysis.py
C:\Users\xxxx.conda\envs\unitraj\lib\site-packages\hydra_internal\defaults_list.py:251: UserWarning: In 'config': Defaults list is missing _self_. See https://hydra.cc/docs/1.2/upgrades/1.0_to_1.1/default_composition_order for more information

train_batch_size = max(cfg.method['train_batch_size'] // len(cfg.devices) // train_set.data_chunk_size, 1)
AttributeError: 'AutoBotDataset' object has no attribute 'data_chunk_size'

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

I’d like to understand what I might have missed. Is there a manual or documentation I can refer to for running python data_analysis.py properly?
