Llama-2-7B-ft-instruct-es

Llama 2 (7B) fine-tuned on Clibrain's Spanish instructions dataset.

Model Details

Llama 2 is a collection of pre-trained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. This is the repository for the 7B pre-trained model. Links to other models can be found in the index at the bottom.

Example of Usage

model_id = "clibrain/Llama-2-7b-ft-instruct-es"

model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True).to("cuda")

    }

    prompt = system_prompt

    for title, content in sections.items():
        if content is not None:
            prompt += f"### {title}:\n{content}\n\n"

Example of Usage with pipelines

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline 

model_id = "clibrain/Llama-2-7b-ft-instruct-es"

model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True).to("cuda")
tokenizer = AutoTokenizer.from_pretrained(model_id)

pipe = pipeline(task="text-generation", model=model, tokenizer=tokenizer, max_length=200, device=0)

prompt = """
A continuación hay una instrucción que describe una tarea. Escriba una respuesta que complete adecuadamente la solicitud.
### Instrucción:
Dame una lista de 5 lugares a visitar en España.

### Respuesta:

result = pipe(prompt)
print(result[0]['generated_text'])
