# Llama-2-7b-ultrachat
|
||
|
|
|
||
|
|
This repo contains a [Llama 2 7B](https://huggingface.co/meta-llama/Llama-2-7b-hf) finetuned for chat tasks using the [UltraChat 200k](https://huggingface.co/datasets/HuggingFaceH4/ultrachat_200k) dataset.

## Usage
|
||
|
|
|
||
|
|
Below we share some code snippets on how to get quickly started with running the model.
|
||
|
|
|
||
|
|
### Sparse Transfer
|
||
|
|
|
||
|
|
By leveraging a pre-sparsified model's structure, you can efficiently fine-tune on new data, leading to reduced hyperparameter tuning, training times, and computational costs. Learn about this process [here](https://neuralmagic.github.io/docs-v2/get-started/transfer).
|
||
|
|
|
||
|
|
### Running the model
|
||
|
|
|
||
|
|
This model may be run with the transformers library. For accelerated inference with sparsity, deploy with [nm-vllm](https://github.com/neuralmagic/nm-vllm) or [deepsparse](https://github.com/neuralmagic/deepsparse).
|
||
|
|
|
||
|
|
```python
|
||
|
|
# pip install transformers accelerate
|
||
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
|
|
||
|
|
tokenizer = AutoTokenizer.from_pretrained("neuralmagic/Llama-2-7b-ultrachat")
|
||
|
|
model = AutoModelForCausalLM.from_pretrained("neuralmagic/Llama-2-7b-ultrachat", device_map="auto")
|
||
|
|
|
||
|
|
input_text = "Write me a poem about Machine Learning."
|
||
|
|
input_ids = tokenizer.apply_chat_template(input_text, add_generation_prompt=True, return_tensors="pt").to("cuda")
|
||
|
|
|
||
|
|
outputs = model.generate(**input_ids)
|
||
|
|
print(tokenizer.decode(outputs[0]))
|
||
|
|
```
|
||
|
|
|
||
|
