uois-toolkit 0.1.2

A toolkit for loading Unseen Object Instance Segmentation (UOIS) datasets.

uois_toolkit

A toolkit for Unseen Object Instance Segmentation (UOIS)

A PyTorch-based toolkit for loading and processing datasets for Unseen Object Instance Segmentation (UOIS). This repository provides a standardized, easy-to-use interface for several popular UOIS datasets, simplifying the process of training and evaluating segmentation models.

Installation

Prerequisites

• Python 3.9+
• An environment manager like conda is recommended.

Steps

1. Clone the repository:

   git clone https://github.com/OnePunchMonk/uois_toolkit.git
   cd uois_toolkit
   

2. Install the package: Installing in editable mode (-e) allows you to modify the source code without reinstalling. The command will automatically handle all necessary dependencies listed in pyproject.toml.

   pip install -e .
   

Note about detectron2

This project depends on detectron2 for some dataset utilities and mask handling. detectron2 includes C++ extensions and must be built for your platform — it cannot always be installed as a pure Python wheel. Please follow the official installation instructions in the Detectron2 meta-repository and install a version compatible with your PyTorch and CUDA (or CPU-only) environment before running the tests or using the datasets:

• Detectron2 installation guide and wheels: https://github.com/facebookresearch/detectron2

On many systems you can install a compatible CPU-only wheel using the prebuilt index, or build from source if needed. If you are running on CI, ensure the runner has the necessary build tools and compatible PyTorch version.

Supported Datasets

This toolkit provides dataloaders for the following datasets:

• Tabletop Object Discovery (TOD)
• OCID
• OSD
• Robot Pushing
• iTeach-HumanPlay

Download Links

• Main Datasets (TOD, OCID, OSD, Robot Pushing):
  • Download from Box
  • Robot Pushing
• iTeach-HumanPlay Dataset:
  • D5: Download
  • D40: Download
  • Test: Download

Directory Setup

It is recommended to organize the downloaded datasets into a single DATA/ directory for convenience, though you can specify the path to each dataset individually.

Usage Example

You can easily import the datamodule into your own projects. The example below demonstrates how to load the tabletop dataset using pytorch-lightning.

from uois_toolkit import get_datamodule, cfg
import pytorch_lightning as pl

# 1. Define the dataset name and its location
dataset_name = "tabletop"
data_path = "/path/to/your/data/tabletop"

# 2. Get the datamodule instance
# The default configuration can be customized by modifying the `cfg` object
data_module = get_datamodule(
    dataset_name=dataset_name,
    data_path=data_path,
    batch_size=4,
    num_workers=2,
    config=cfg
)

# 3. The datamodule is ready to be used with a PyTorch Lightning Trainer
# model = YourLightningModel()
# trainer = pl.Trainer(accelerator="auto")
# trainer.fit(model, datamodule=data_module)

# Alternatively, you can inspect a data batch directly
data_module.setup()
train_loader = data_module.train_dataloader()
batch = next(iter(train_loader))

print(f"Successfully loaded a batch from the {dataset_name} dataset!")
print("Image tensor shape:", batch["image_color"].shape)

Testing

Local Validation

The repository includes a pytest suite to verify that the dataloaders and processing pipelines are working correctly.

To run the tests, you must provide the root paths to your downloaded datasets using the --dataset_path argument.

python -m pytest test/test_datamodule.py -v \
  --dataset_path tabletop=/path/to/your/data/tabletop \
  --dataset_path ocid=/path/to/your/data/ocid \
  --dataset_path osd=/path/to/your/data/osd
  # Add other dataset paths as needed

Note: You only need to provide paths for the datasets you wish to test.

Continuous Integration

This repository uses GitHub Actions to perform automated sanity checks on every push and pull request to the main branch. This workflow ensures that:

1. The package installs correctly.
2. The code adheres to basic linting standards.
3. All core modules remain importable.

This automated process helps maintain code quality and prevents the introduction of breaking changes.
