Gemma Coder 👩💻
Gemma 2B fine-tuned on the CodeAlpaca 20k instructions dataset by using the method QLoRA with PEFT library.
Model description 🧠
Gemma is a family of lightweight, state-of-the-art open models from Google, built from the same research and technology used to create the Gemini models. They are text-to-text, decoder-only large language models, available in English, with open weights, pre-trained variants, and instruction-tuned variants. Gemma models are well-suited for a variety of text generation tasks, including question answering, summarization, and reasoning. Their relatively small size makes it possible to deploy them in environments with limited resources such as a laptop, desktop or your own cloud infrastructure, democratizing access to state of the art AI models and helping foster innovation for everyone.

Example of usage 👩💻
I recommend install the following version of torch:
pip install "torch>=2.1.1" -U
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
model_id = "MAISAAI/gemma-2b-coder"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id).to("cuda")
def generate(
instruction,
max_new_tokens=256,
temperature=0.1,
top_p=0.75,
top_k=40,
num_beams=2,
**kwargs,
):
system = f"<bos><|system|>\nYou are a helpful coding assistant.<eos>\n"
prompt = f"{system}<|user|>\n{instruction}<eos>\n<|assistant|>\n"
inputs = tokenizer(prompt, return_tensors="pt")
input_ids = inputs["input_ids"].to("cuda")
attention_mask = inputs["attention_mask"].to("cuda")
generation_config = GenerationConfig(
temperature=temperature,
top_p=top_p,
top_k=top_k,
num_beams=num_beams,
**kwargs,
)
with torch.no_grad():
generation_output = model.generate(
input_ids=input_ids,
attention_mask=attention_mask,
generation_config=generation_config,
return_dict_in_generate=True,
max_new_tokens=max_new_tokens,
early_stopping=True
)
s = generation_output.sequences[0]
output = tokenizer.decode(s, skip_special_tokens=True)
return output.split("<|assistant|>")[1]
instruction = """

"""
print(generate(instruction))
