@Maki9009 Okay so i found a fix the metadata files that whisper model was creating had empty lines mainly metadata_eval.csv in the directory finetune_model/dataset/.

To fix this error you need to delete the dataset folder and try creating the dataset again using different whisper models in my case large and medium did work while the other models were having empty lines into the metadata dataset files.
