Fine tuning CHGNet with DFT energies and forces

[Atefeh-Yadegarifard]

Dear CHGNet developers,
Hello.
I would like to request an example for how CHGNet can be trained with additional DFT data (calculated by the users). Specifically the format of the data that has to be used for training.
Thank you.
