Usage Example
Here's a Python code snippet demonstrating how to interact with the ai-medical-model-32bit
model and generate answers to your medical questions:
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
import torch
model_name = "ruslanmv/ai-medical-model-32bit"
device_map = 'auto'
bnb_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.float16,
)
model = AutoModelForCausalLM.from_pretrained(
model_name,
quantization_config=bnb_config,
trust_remote_code=True,
use_cache=False,
device_map=device_map
)
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
tokenizer.pad_token = tokenizer.eos_token
def askme(question):
prompt = f"<|start_header_id|>system<|end_header_id|> You are a Medical AI chatbot assistant. <|eot_id|><|start_header_id|>User: <|end_header_id|>This is the question: {question}<|eot_id|>"
# Tokenizing the input and generating the output
#prompt = f"{question}"
# Tokenizing the input and generating the output
inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=256, use_cache=True)
answer = tokenizer.batch_decode(outputs, skip_special_tokens=True)[0]
# Try Remove the prompt
try:
# Split the answer at the first line break, assuming system intro and question are on separate lines
answer_parts = answer.split("\n", 1)
# If there are multiple parts, consider the second part as the answer
if len(answer_parts) > 1:
answers = answer_parts[1].strip() # Remove leading/trailing whitespaces
else:
answers = "" # If no split possible, set answer to empty string
print(f"Answer: {answers}")
except:
print(answer)
# Example usage
# - Question: Make the question.
question="What was the main cause of the inflammatory CD4+ T cells?"
askme(question)
the type of answer is :
Answer: I'm happy to help!
The main cause of inflammatory CD4+ T cells is a complex process that involves multiple factors. However, some of the key triggers include:
1. Activation of CD4+ T cells: CD4+ T cells are activated by antigens, cytokines, and other signals, leading to their proliferation and differentiation into effector cells.
2. Cytokine production: Activated CD4+ T cells produce cytokines such as interleukin-2 (IL-2), interferon-gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α), which promote inflammation and immune responses.
3. Chemokine production: CD4+ T cells also produce chemokines, such as CCL3, CCL4, and CCL5, which attract other immune cells to the site of inflammation.
4. Toll-like receptor (TLR) activation: TLRs are pattern recognition receptors that recognize pathogen-associated molecular patterns (PAMPs) and activate CD4+ T cells.
5. Bacterial or viral infections: Infections caused by bacteria, viruses, or fungi can trigger the activation of CD4+ T cells and the production of cytokines and chemokines
