Quickstart

from transformers import GPT2LMHeadModel, GPT2Tokenizer


path = "jianghc/medical_chatbot"
device = "cuda" if torch.cuda.is_available() else "cpu"
tokenizer = GPT2Tokenizer.from_pretrained(path)
model = GPT2LMHeadModel.from_pretrained(path).to(device)

prompt_input = (
    "The conversation between human and AI assistant.\n"
    "[|Human|] {input}\n"
    "[|AI|]"
)
sentence = prompt_input.format_map({'input': "what is parkinson's disease?"})
inputs = tokenizer(sentence, return_tensors="pt").to(device)

with torch.no_grad():
    beam_output = model.generate(**inputs,
                                min_new_tokens=1,
