How to use

from transformers import pipeline

pipe = pipeline("summarization", model="sharmax-vikas/flan-t5-base-samsum")

res = pipe('''dialogue: 
Margaret: Hi, in December I'd like to meet on 4th and 11th around 10:00 or 11:00. 
Evans: Hi, 4th - we can meet at 10:00.
Evans: And 11th - at 11:00. 
Margaret: Okey. And what about 18th?
Evans: I'm not sure about 18th. 
Evans: I might not be in town. 
Margaret: Okey, so we'll see. 
Evans: Yes. And I'll let you know next week. 
Margaret: If it's not 18th, maybe we could meet on 17th?
Evans: If I go away, I won't also be 17th.
Margaret: Okey, I get it. 
Evans: But we could meet 14th, if you like?
Margaret: Hm, I'm not sure whether I'm avaliable. 
Evans: So let's set these dates later, ok?
Margaret: Okey and we see each other 4th 10:00. 
Evans: Yes!''')

print(f"flan-t5-base summary:\n{res[0]['summary_text']}")


#output : flan-t5-base summary:
Margaret and Evans will meet on the 4th and 11th of December. They will meet at 10:00 on the 18th and at 11:00 on the 17th. If it's not 18th, they can meet on 17th or 14th.
