The default of the "text_generated_model_name"

[Nyx-Feng]

The default of the original parser's of the argument "text_generated_model_name" is "gpt2", and it would have error when we try to traversal it, like key 'g' is not exist. So I assume it should be as an element, like alter to : default = ['gpt2'] ?
