**Usage HuggingFace Transformers for header generation task**
``` 
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
model = AutoModelForSeq2SeqLM.from_pretrained("AlekseyKulnevich/Pegasus-HeaderGeneration")
tokenizer = PegasusTokenizer.from_pretrained('google/pegasus-large')

input_ = tokenizer.batch_encode_plus([input_text], max_length=1024, pad_to_max_length=True, 
                truncation=True, padding='longest', return_tensors='pt')
input_ids = input_['input_ids'] 
input_mask = input_['attention_mask']
headers = model.generate(input_ids=input_ids, 
                         attention_mask=input_mask,

Also you can play with the following parameters in generate method:   
-top_k  
-top_p
