Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Advanced configuration options and less common models are not well-documented, leading to difficulties in customization.
The library can become slow when processing very large images or datasets due to memory constraints and inefficient batch handling.
Limited number of contributors and a small user base means fewer resources, slower bug fixes, and less community-driven development.
Frequent breaking changes between minor version updates can disrupt ongoing projects and require significant refactoring efforts.
