Hi,
The scripts are meant as examples, you can easily tweak them to make it work with your local dataset.
For instance, you can load a HuggingFace Dataset with your local data (as explained in the docs 1), which could be CSV, JSON, txt, Parquet, etc.
Just make sure that you prepare your data in IOB format (as this is required for the token classification models).
If you can provide me with a small portion, I can illustrate how to make a HuggingFace Dataset with it, and make it work with the script.
