Question: File format and structure of the DHP19 dataset in this project

[yingjiezero]

Dear Robotics and Perception Group:
Thank you for sharing this amazing project! I am currently trying to run the code but have encountered an issue related to the dataset. I noticed that the project uses the DHP19 dataset, but I am unsure of the expected file format and directory structure when using this dataset in your code.

When I run train_cnn_snn_hybrid_model.py, I encounter the following error:
AssertionError: datasets should not be an empty iterable.

Below are my config settings and the dataset directory structure for DHP19.

Could you please clarify the following points?

What file format should be used for the dataset (e.g. .aedat or other format)?
How should the directories and files of the dataset be organised?
I have referred to the README and the codebase, but have not found any detailed information on this. Your guidance would be greatly appreciated!

Thank you for your valuable time and for open sourcing this project.

Best regards,
Xinyu Li
