## Model Card for Model ID

This repository contains a LLaMA-7B further fine-tuned model on conversations and question answering prompts.

This model is a fine-tuned version of [chainyo/alpaca-lora-7b](https://huggingface.co/chainyo/alpaca-lora-7b) on conversations dataset.

⚠️ **I used [LLaMA-7b-hf](https://huggingface.co/decapoda-research/llama-7b-hf) as a base model, so this model is for Research purpose only (See the [license](https://huggingface.co/decapoda-research/llama-7b-hf/blob/main/LICENSE))**

## Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.


# Usage

## Creating prompt

The model was trained on the following kind of prompt:

```python
def generate_prompt(instruction: str, input_ctxt: str = None) -> str:
 if input_ctxt:
 return f"""Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
{instruction}

### Input:
{input_ctxt}

### Response:"""
 else:
 return f"""Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
{instruction}

### Response:"""
```

## How to Get Started with the Model

Use the code below to get started with the model.

```python
from transformers import LlamaTokenizer, LlamaForCausalLM
from peft import PeftModel

MODEL_NAME = "decapoda-research/llama-7b-hf"
tokenizer = LlamaTokenizer.from_pretrained(MODEL_NAME, add_eos_token=True)
tokenizer.pad_token_id = 0

model = LlamaForCausalLM.from_pretrained(MODEL_NAME, load_in_8bit=True, device_map="auto")
model = PeftModel.from_pretrained(model, "Sandiago21/llama-7b-hf")
```

### Example of Usage
```python
from transformers import GenerationConfig

PROMPT = """Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.\n\n### Instruction:\nWhich is the capital city of Greece and with which countries does Greece border?\n\n### Input:\nQuestion answering\n\n### Response:\n"""
DEVICE = "cuda"

inputs = tokenizer(
 PROMPT,
 return_tensors="pt",
)

input_ids = inputs["input_ids"].to(DEVICE)

generation_config = GenerationConfig(
 temperature=0.1,
 top_p=0.95,
 repetition_penalty=1.2,
)

print("Generating Response ... ")
with torch.no_grad():
 generation_output = model.generate(
 input_ids=input_ids,
 generation_config=generation_config,
 return_dict_in_generate=True,
 output_scores=True,
 max_new_tokens=256,
 )

for s in generation_output.sequences:
 print(tokenizer.decode(s))
```

### Example Output
```python
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
Which is the capital city of Greece and with which countries does Greece border?

### Input:
Question answering

### Response:

 
Generating...
<unk> Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
Which is the capital city of Greece and with which countries does Greece border?

### Input:
Question answering

### Response:
<unk>capital city of Athens and it borders Albania to the northwest, North Macedonia and Bulgaria to the northeast, Turkey to the east, and Libya to the southeast across the Mediterranean Sea.
```
