MedicalChat-Phi-3.5-mini-instruct

🏥 Phi-3.5 Mini Instruct Medical Chat (LoRA Adapter)

The MedicalChat-Phi-3.5-mini-instruct- fine-tuned model is designed to simulate doctor-patient conversations, offering medical consultations and suggestions based on patient queries. However, its accuracy may be limited in real-world scenarios, as the training dataset was relatively small.

🚀 How to Get Started

Install Required Packages

!pip install transformers peft accelerate torch bitsandbytes

Load and Use the Model

Since inference requires more memory, the model will be loaded and inference will be performed on the CPU.

from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline
import torch

# Clear CUDA memory before using the model
torch.cuda.empty_cache()

device = "cuda" if torch.cuda.is_available() else "cpu"

model_name = "syubraj/MedicalChat-Phi-3.5-mini-instruct"

try:
    model = AutoModelForCausalLM.from_pretrained(model_name, trust_remote_code = True)
    tokenizer = AutoTokenizer.from_pretrained(model_name)
    print("Model and Tokenizer loaded successfully.")
except Exception as e:
    raise ValueError(f"Error loading Model and Tokenizer: {e}")

    :param user_query: The user's input message.
    :param system_message: Custom system instruction (optional, defaults to medical assistant).
    :param max_length: Max tokens to generate.
    :return: Generated assistant response.

📝 Example Output

Assistant Response: Hello! I understand that you're looking to potentially increase your height, and I'll do my best to provide you with helpful information.

Firstly, it's important to clarify that after puberty, the growth plates in our bones, known as epiphyseal plates, have typically fused, meaning our height generally stabilizes. For most adults, especially those who have reached their late teens or early twenties, further height increase is unlikely.

However, there are a few factors that can influence your height:

1. Genetics: Your genes play a significant role in determining your height. If your parents are tall, you might be taller too.

2. Nutrition: Proper nutrition is essential for growth. Ensure you're getting a balanced diet with enough protein, calcium, and vitamins.

3. Posture: Sometimes, poor posture can make you appear shorter. Practicing good posture might help you look taller.

4. Sleep: Adequate sleep is crucial for growth hormones to work effectively.

5. Exercise: Regular exercise can help maintain a healthy posture and spine alignment, which might help you appear taller.

Here are some tips that might help you look taller:

• Stand Straight: Keep your shoulders back and your back straight. This can make you appear taller.

• Practice Good Posture: Be mindful of your posture throughout the day.

• Exercise: Engage in exercises that strengthen your core, back, and leg muscles.

• Shoe Lifts: Some people find that wearing shoe lifts can make them appear taller. However, this is more of a visual effect and won't actually increase your height.

• Physical Therapy: If you have concerns about your posture or spinal alignment, a physical therapist can provide exercises and treatments to help.

Remember, while these tips might help you look taller, they won't change your actual height. If you're concerned about your height for medical reasons, such as a growth hormone deficiency, it's best to consult with a healthcare provider.

I hope this information is helpful! If you have any more questions or need further assistance, feel free to ask.
