Medical Chatbot

🚀 醫療聊天機器人

本聊天機器人專為研究目的設計，可提供醫療相關信息，但不能替代專業醫療建議。

⚠️ 重要提示

請注意，此聊天機器人僅用於研究目的，不適合在實際醫療環境中使用。儘管該聊天機器人經過訓練，能夠提供準確且有用的回覆，但它不能替代專業的醫療建議、診斷或治療。聊天機器人提供的信息不應被用於做出醫療決策，任何健康問題都應諮詢有資質的醫療服務提供者。

🚀 快速開始

以下是使用該醫療聊天機器人的示例代碼：

import torch
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, 
                                max_length=512,
                                num_beams=3,
                                repetition_penalty=1.2,
                                early_stopping=True,
                                eos_token_id=198 
                                )
    print(tokenizer.decode(beam_output[0], skip_special_tokens=True))

基礎用法

以下是使用聊天機器人詢問帕金森病相關問題的示例：

import torch
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, 
                                max_length=512,
                                num_beams=3,
                                repetition_penalty=1.2,
                                early_stopping=True,
                                eos_token_id=198 
                                )
    print(tokenizer.decode(beam_output[0], skip_special_tokens=True))

示例輸出

The conversation between human and AI assistant.
[|Human|] what is parkinson's disease?
[|AI|] Parkinson's disease is a neurodegenerative disorder that affects movement. It is caused by the loss of dopamine-producing cells in the brain.

The conversation between human and AI assistant.
[|Human|] what type of honey is best for a bad covid cough?
