LlamaPy is a Python project for natural language processing tasks using a custom model called LLaMA3. This model is designed for tokenization and language generation tasks.
- Transformer-based architecture
- Multi-head attention mechanism
- Multiple layers for hierarchical representation learning
- Long-range sequence modeling capabilities
- Dependencies: LlamaPy relies on the following Python libraries:
torch
for deep learning computationsnltk
for natural language processing tasks such as tokenizationtqdm
for progress tracking during training
- Model Parameters:
hidden_dim
: Dimensionality of the model's hidden statesnum_heads
: Number of attention heads in the multi-head attention mechanismnum_layers
: Number of layers in the transformer architecturemax_length
: Maximum sequence length supported by the model
- Training Procedure:
- The model is trained using an Adam optimizer with a cross-entropy loss function.
- Training data is fed to the model in batches, with a specified batch size and sequence length.
- Training progresses over multiple epochs, with progress tracked using the tqdm library.
To use LlamaPy, you need to install the required dependencies. You can install them using pip:
pip install tqdm nltk torch
You also need to download the NLTK corpora. Run the following commands after installing NLTK:
import nltk
nltk.download('punkt')
nltk.download('gutenberg')
Here's a brief overview of how to use LlamaPy:
- Import the necessary modules:
import subprocess
import nltk
from tqdm import tqdm
import torch
Next, run the code in a jupyter notebook, which would train the llama3 model on nltk's gutenberg corpus.
-
Model Initialization:
- Initialize the LLaMA3 model with appropriate parameters such as vocabulary size, hidden dimension, number of heads, and number of layers.
-
Training:
- Train the model using your dataset by feeding tokenized sequences to the model in batches.
- Adjust training parameters such as batch size, sequence length, learning rate, and number of epochs as needed.
-
Inference:
- Once trained, use the model for text generation or other natural language processing tasks.
- Provide input sequences to the model and obtain predictions for the next tokens.
