-
|
| 41 |
-
### 1. `TRAINER.ipynb`
|
| 42 |
-
|
| 43 |
-
This notebook is responsible for training a language model with LoRA adapters using the Unsloth library. The core functionality includes:
|
| 44 |
-
- Loading a pre-trained model from Hugging Face using `FastLanguageModel`.
|
| 45 |
-
- Attaching LoRA adapters for efficient fine-tuning of large models.
|
| 46 |
-
- Setting training configurations (e.g., learning rate, number of epochs, batch size) using the `SFTTrainer` from the `transformers` library.
|
| 47 |
-
- Optionally, resuming training from the last checkpoint.
|
| 48 |
-
- Uploading checkpoints and models to Hugging Face during or after training.
|
| 49 |
-
|
| 50 |
-
#### How to Use:
|
| 51 |
-
1. Open this notebook in Google Colab or a similar environment.
|
| 52 |
-
2. Ensure you have set up your Hugging Face token (refer to the section below for setup).
|
| 53 |
-
3. Customize the training parameters if needed.
|
| 54 |
-
4. Run the notebook cells to train the model.
|
| 55 |
-
|
| 56 |
-
### 2. `TESTER.ipynb`
|
| 57 |
-
|
| 58 |
-
This notebook handles the evaluation of a fine-tuned model. It allows testing the model's accuracy and efficiency on a test dataset using pre-defined metrics like accuracy, precision, recall, and F1 score. It provides the following functionalities:
|
| 59 |
-
- Loads the fine-tuned model with its LoRA adapters.
|
| 60 |
-
- Defines a function to evaluate the model's predictions on a test dataset.
|
| 61 |
-
- Outputs accuracy and other classification metrics.
|
| 62 |
-
- Displays confusion matrices for better insight into model performance.
|
| 63 |
-
|
| 64 |
-
#### How to Use:
|
| 65 |
-
1. Load this notebook in your environment.
|
| 66 |
-
2. Specify the test dataset and model details.
|
| 67 |
-
3. Run the evaluation loop to get accuracy, predictions, and metrics visualizations.
|
| 68 |
-
|
| 69 |
-
### 3. `dataFormat.ipynb`
|
| 70 |
-
|
| 71 |
-
This notebook formats datasets into the correct structure for training and testing models. It provides functionality to map raw text data into a format suitable for language model training, particularly for multi-turn conversations:
|
| 72 |
-
- Formats conversations into a chat-based template using Unsloth's `chat_templates`.
|
| 73 |
-
- Maps data fields like "role", "content", and user/assistant conversations.
|
| 74 |
-
- Prepares the dataset for tokenization and input to the model.
|
| 75 |
-
|
| 76 |
-
#### How to Use:
|
| 77 |
-
1. Open the notebook and specify the dataset you wish to format.
|
| 78 |
-
2. Adjust any template settings based on the model you're using.
|
| 79 |
-
3. Run the notebook to output the formatted dataset.

## Usage
|
| 84 |
-
|
| 85 |

### Environment Setup
|
| 86 |
-
|
| 87 |
-
1. **Install Unsloth**:
|
| 88 |
-
The following command is included in the notebooks to install Unsloth:
|
| 89 |
-
```bash
|
| 90 |
-
!pip install "unsloth[colab-new] @ git+https://github.com/unslothai/unsloth.git"
|
| 91 |
-
```
|
| 92 |
-
|
| 93 |
-
2. **Install Additional Dependencies**:
|
| 94 |
-
These dependencies are also required:
|
| 95 |
-
```bash
|
| 96 |
-
!pip install --no-deps xformers==0.0.27 trl peft accelerate bitsandbytes triton
|
| 97 |
-
```
|
| 98 |
-
|
| 99 |
-
3. **Hugging Face Token Setup**:
|
| 100 |
-
- Add your Hugging Face token as an environment variable in Google Colab or in your local environment.
|
| 101 |
-
- Use the Hugging Face token to download models and upload checkpoints:
|
| 102 |
-
```python
|
| 103 |
-
from google.colab import userdata
|
| 104 |
-
from huggingface_hub import login
|
| 105 |
-
login(userdata.get('TOKEN'))
|
| 106 |
-
```
|

|
| 113 |
-
4. Run the notebook to start the training process.
|
| 114 |
-
|
| 115 |

The model will automatically be saved at checkpoints and uploaded to Hugging Face.
|
| 116 |
-
|
| 117 |
-
### Testing the Model

|
| 121 |
-
3. Specify a test dataset in the appropriate format.
|
| 122 |
-

|
| 123 |
-
|
| 124 |
-
### Formatting Data
|
| 125 |
-
|
| 126 |
-
1. Use `dataFormat.ipynb` to format raw data into a training-friendly structure.
|
| 127 |
-
2. Map the conversation fields using the `formatting_prompts_func`.
|
| 128 |
-
3. Output the formatted data and use it in the training or testing notebooks.
