Manipulating how a sample should start

[fabpapi]

Hi, I have been trying to add a 'Prefix' to the parameters in order to be able to tell the model how to start the beginning of a sample (something like https://github.com/minimaxir/gpt-2-simple did). Unfortunately, I failed. Do you have any idea on what to add into the 'interactive_conditional_samples.py'?

Thank you so much,

Fabrizio
