Extending

There are few ways to extend and customize Datumaro behavior, which is supported by plugins. Check our contribution guide for details on plugin implementation. In general, a plugin is a Python code file. It must be put into a plugin directory:

  • <project_dir>/.datumaro/plugins for project-specific plugins
  • <datumaro_dir>/plugins for global plugins

Built-in plugins

Datumaro provides several builtin plugins. Plugins can have dependencies, which need to be installed separately.

TensorFlow

The plugin provides support of TensorFlow Detection API format, which includes boxes and masks. It depends on TensorFlow, which can be installed with pip:

pip install tensorflow
# or
pip install tensorflow-gpu
# or
pip install datumaro[tf]
# or
pip install datumaro[tf-gpu]

Accuracy Checker

This plugin allows to use Accuracy Checker to launch deep learning models from various frameworks (Caffe, MxNet, PyTorch, OpenVINO, …) through Accuracy Checker’s API. The plugin depends on Accuracy Checker, which can be installed with pip:

pip install 'git+https://github.com/openvinotoolkit/open_model_zoo.git#subdirectory=tools/accuracy_checker'

OpenVINO™

This plugin provides support for model inference with OpenVINO™. The plugin depends on the OpenVINO™ Toolkit, which can be installed by following these instructions

Dataset Formats

Dataset reading is supported by Extractors and Importers. An Extractor produces a list of dataset items corresponding to the dataset. An Importer creates a project from the data source location. It is possible to add custom Extractors and Importers. To do this, you need to put an Extractor and Importer implementation scripts to a plugin directory.

Dataset writing is supported by Converters. A Converter produces a dataset of a specific format from dataset items. It is possible to add custom Converters. To do this, you need to put a Converter implementation script to a plugin directory.

Dataset Conversions (“Transforms”)

A Transform is a function for altering a dataset and producing a new one. It can update dataset items, annotations, classes, and other properties. A list of available transforms for dataset conversions can be extended by adding a Transform implementation script into a plugin directory.

Model launchers

A list of available launchers for model execution can be extended by adding a Launcher implementation script into a plugin directory.
