Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The one-line approach restricts users from fine-tuning network architectures beyond basic configurations.
Official documentation lacks detailed examples and explanations for complex use cases, leading to a steep learning curve.
GitHub issues are infrequently addressed by maintainers, and the user base is relatively small compared to more established frameworks like TensorFlow or PyTorch.
