# JVM Troubleshooting Assistant

## Model Description

This is a fine-tuned conversational AI model specialized in JVM (Java Virtual Machine) troubleshooting and performance optimization. The model has been trained on domain-specific Q&A pairs generated from JVM troubleshooting documentation to provide expert-level assistance with Java application issues.

- **Developed by:** CesarChaMal
- **Model type:** Conversational AI / Question-Answering
- **Language(s):** English
- **License:** MIT
- **Finetuned from model:** microsoft/DialoGPT-small

## Model Sources

- **Repository:** https://github.com/CesarChaMal/python_process_custom_data_from_pdf
- **Dataset:** https://huggingface.co/datasets/CesarChaMal/jvm_troubleshooting_guide

## Uses

### Direct Use

This model is designed for:
- **JVM Troubleshooting:** Diagnosing memory issues, OutOfMemoryErrors, and performance problems
- **Performance Optimization:** Recommending JVM parameters and tuning strategies  
- **Technical Support:** Providing expert guidance on Java application issues
- **Educational Purposes:** Teaching JVM concepts and best practices

### Example Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("CesarChaMal/jvm_troubleshooting_model")
model = AutoModelForCausalLM.from_pretrained("CesarChaMal/jvm_troubleshooting_model")

# Format your question
question = "What are common JVM memory issues?"
input_text = f"### Human: {question}\n### Assistant:"

# Generate response
inputs = tokenizer(input_text, return_tensors='pt')
outputs = model.generate(**inputs, max_new_tokens=150, temperature=0.7)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response.split("### Assistant:")[-1].strip())
```

### Out-of-Scope Use

- **General Programming Questions:** Not optimized for non-JVM related programming issues
- **Production Critical Decisions:** Always verify recommendations with official documentation

## How to Get Started

### Installation

```bash
pip install transformers torch
```

### Quick Start

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model and tokenizer
model_name = "CesarChaMal/jvm_troubleshooting_model"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Ask a question
question = "How do I troubleshoot OutOfMemoryError?"
input_text = f"### Human: {question}\n### Assistant:"

# Generate response
inputs = tokenizer(input_text, return_tensors='pt', truncation=True, max_length=512)
with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=150,
        temperature=0.7,
        do_sample=True,
        pad_token_id=tokenizer.eos_token_id
    )

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
answer = response.split("### Assistant:")[-1].strip()
print(answer)
```
