LORA Data Tool - Windows Universal Edition (v1.2 CPU-Only)

Developed by jazara930, based on Sarcastic TOFU's original script

This new Universal CPU Edition is a major update specifically optimized for Windows users. While the previous GPU version works great for many, we recognized that the Windows ecosystem presents too many variables—different GPU architectures, conflicting CUDA versions, and varying driver updates—that often lead to instability.

Why a CPU-Only version? Developing a stable GPU tool for everyone would require separate optimizations for every single combination of NVIDIA drivers and hardware. To solve this, we created this CPU version: it eliminates the white screen crashes, WinError 126 (DLL issues), and VRAM limitations. By using your system's processor, we ensure the tool runs successfully on any PC or laptop.

Key Features of this Build:

• Standalone & Portable: No need to install Python or Git.

• Pre-Downloaded Model: Florence-2 AI is already included.

• Maximum Stability: Rebuilt from scratch with Python 3.11.9.

How to get started:

1. Extract the entire folder from the ZIP file to your Desktop.

2. Open the folder and run: Avvio_Lora_Tool_v1.2_CPU_version.bat.

3. Test it: Select the Dataset/Sample_Images folder and click Start Processing.

Overview GPU Version

This is a Portable Windows version of the Florence-2 LORA Data Builder, specifically optimized for NVIDIA RTX GPUs (tested on RTX 3090). It allows you to generate high-quality captions for your LORA datasets using the Florence-2 model without any complex installation.
