Description

This repository contains LoRA (Low-Rank Adaptation) adapter weights for fine-tuning a Gemma 7B model on a custom dataset.

Important: This is NOT a full model release. It only includes the LoRA adapter weights and a config.json to guide loading the model. You will need to write custom code to load the base Gemma model and apply the adapters.

Model Fine-tuning Details

• Base Model: google/gemma2_9b_en
• Fine-tuning Method: LoRA (Low-Rank Adaptation)
• LoRA Rank: 8
• Dataset:
• Training Framework: KerasNLP

How to Use

This release is not directly compatible with the transformers library's standard loading methods. You will need to:

1. Load the Base Gemma Model: Use KerasNLP to load the google/gemma2_9b_en base model. Make sure you have the KerasNLP library installed and properly configured.

2. Enable LoRA: Utilize KerasNLP’s LoRA functionality to enable adapters on the appropriate layers of the Gemma model. Refer to the KerasNLP LoRA documentation for implementation details.

3. Load Adapter Weights: Load the adapter_model.bin and other relevant files from this repository. The config.json file provides essential configurations for applying the LoRA adapter weights.

4. Integration: Integrate this custom loading process into your Hugging Face Transformers-based code. Ensure you handle the merging of adapter weights with the base model appropriately.

Example Code Structure (Conceptual):

import keras_nlp
from transformers import GemmaTokenizerFast  # Or the appropriate tokenizer from KerasNLP

# Load the base Gemma model using KerasNLP
base_model = keras_nlp.models.Gemma.from_pretrained('google/gemma2_9b_en')

# Enable LoRA adapters on target layers
# Assuming you have a function to enable LoRA, e.g., enable_lora(model, rank)
enable_lora(base_model, rank=8)

# Load adapter weights from this repository
# Assuming you have a function to load the weights, e.g., load_lora_weights(model, weights_path)
adapter_weights_path = 'path_to_your_adapter_weights/adapter_model.bin'
load_lora_weights(base_model, adapter_weights_path)

# Initialize tokenizer
tokenizer = GemmaTokenizerFast.from_pretrained('google/gemma2_9b_en')

# Use the tokenizer and model for generation or other tasks
inputs = tokenizer("Your input text", return_tensors="pt")
outputs = base_model.generate(**inputs)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Requirements

• KerasNLP: Install using pip install keras-nlp
• Transformers: Install using pip install transformers
• Other Dependencies: Ensure all dependencies required for KerasNLP and Hugging Face Transformers are installed.

Notes

• Ensure you have the correct versions of KerasNLP and Transformers compatible with each other.
• Custom code for loading and applying LoRA adapters may require adjustments based on your specific use case and the versions of libraries used.
