dotadevkit 1.3.0

DOTA Devkit

About

This is a modified version of the original DOTA_Devkit. The devkit has had some issues regarding ease of installation and usage with the latter being a significant problem. This repo attemps to address these issues by providing a simple CLI for easier usage and cross-platform whls for easier installation.

Disclaimer: This repo was created post 9938855. The DOTA authors could update the original repo and/or add support for (possible) new versions of the DOTA dataset. While this repo will try to remain in sync with the original, users should rely on the original should the repos diverge.
