-app.py – Quranic Data Training Pipeline Endpoint for ZeroGPU Spaces
---------------------------------------------------------------------
-This script integrates a full Quranic data processing and training pipeline
-into a Gradio interface endpoint. It is optimized for CPU/GPU-based training 
-on Hugging Face ZeroGPU (using the Gradio SDK) and uses chunked incremental 
-training, memory management, and gradient checkpointing to efficiently update 
-Google's Gemma-2-2b model with Quranic data.
-
-Requirements:
- - Transformers (>=4.42.0)
- - Gradio (>=5.12.0)
- - PyTorch (==2.2.2)
- - psutil (==5.9.5)
- - Accelerate (>=0.26.0)
- - Hugging Face PRO subscription with ZeroGPU enabled (ensure your HF token is set as an environment variable HF_TOKEN)
- - Ubuntu CPU/Linux with access to ZeroGPU hardware via Spaces
- - Input data files placed in the project root.
- - Sufficient storage in "working_directory"
