How to set hyperparameters?

[hzhz2020]

Dear Author,

thank you for the exciting work! I am new to this topic, but is fascinated by your work, and try to understand it better.
In your provided example, how do i set the max_new_tokens and num_beams? How does this value affect the output quality?

Step 4: Generate text
"""
generated_text = model.generate(
vision_x=vision_x,
lang_x=lang_x["input_ids"],
attention_mask=lang_x["attention_mask"],
max_new_tokens=20,
num_beams=3,
)
