> While we strive to present as many use cases as possible, the example scripts are just that - examples. It is expected that they won't work out-of-the box on your specific problem and that you will be required to change a few lines of code to adapt them to your needs. To help you with that, most of the examples fully expose the preprocessing of the data, allowing you to tweak and edit them as required.

To that end, we don't intend  to add additional features to existing scripts. However, feel free to upload a gist somewhere with the code that you have and share it on the [forum](https://discuss.huggingface.co), I'm sure some users would love to see it!

Thanks!
