ptyolox-garage 0.2.1

A practical GUI and Python toolkit for Pixeltable YOLOX

PTYOLOX Garage

日本語

PTYOLOX Garage is a practical desktop and Python toolkit for training, testing, and exporting object-detection models with Pixeltable YOLOX. It provides an Ultralytics-style API and a bilingual tkinter GUI for repeatable local and offline workflows.

Features

• Prepare Label Studio COCO exports for training
• Train YOLOX nano, tiny, s, m, l, and x models with staged epoch schedules
• Run inference on images, NumPy arrays, directories, and USB cameras
• Export trained models to ONNX
• Switch the GUI between English and Japanese
• Store reusable CPU/GPU configuration profiles

Requirements

• Python 3.10–3.13
• Windows 11 is the primary supported platform
• NVIDIA CUDA GPU is recommended for training; CPU inference is supported

On Linux, tkinter may need to be installed through the operating-system package manager.

Installation

From PyPI:

pip install ptyolox-garage

For development with uv:

git clone https://github.com/Moge800/ptyolox-garage.git
cd ptyolox-garage
uv sync --group dev

PyTorch builds are hardware-specific. Install the appropriate PyTorch build from the official selector when CUDA support is required.

Model Security

PyTorch checkpoint files such as .pt can execute arbitrary code when loaded. Only open model files from a trusted source. The GUI asks for confirmation before loading a model file; cancel the dialog when you cannot verify its origin.

GUI

ptyolox-garage

The GUI contains four work areas: training, image inference, live camera inference, and ONNX export. The initial language follows the operating-system locale and can be changed from the Language menu.

Configuration is stored in the operating system's user configuration directory. On Windows, the default location is %APPDATA%\ptyolox-garage\config.ini.

Python API

from ptyolox_garage import YOLOX

# Train from a Label Studio COCO export.
model = YOLOX("l")
model.train(
    data="data.yaml",
    epochs=[100, 200, 300],
    device="cuda:0",
    batch=16,
)

# Run inference.
model = YOLOX("best_model.pt")
results = model.predict("image.jpg", conf=0.3)
annotated = results[0].plot()

# Export to ONNX.
model.export(format="onnx")

Dataset Configuration

data.yaml points to a Label Studio COCO export and its image directory:

coco_json: C:/datasets/widgets/result.json
images_dir: C:/datasets/widgets/images
output_dir: C:/datasets/widgets/prepared
val_split: 0.2

PTYOLOX Garage remaps COCO category IDs, validates image paths, creates train/validation splits, and writes the directory structure expected by Pixeltable YOLOX.

Model Sizes

Name	Depth	Width
nano	0.33	0.25
tiny	0.33	0.375
s	0.33	0.50
m	0.67	0.75
l	1.00	1.00
x	1.33	1.25

Development

uv sync --group dev
uv run pytest
uv run ruff check .
uv build

Detailed guides are available in the English documentation and Japanese documentation.
