Hello. I am trying to integrate the results of a LDA topic model and controlled-text generation, which is usually a set of keywords, to generate readable semantics/sentences. I have read some relevant papers and tried the codes at ‘transformers/examples/text-generation/pplm’ and ‘run_geneartion’, but still struggling to understand how to input “a list of strings” as input instead of a single string as the demo presents. Thank you!
