Strengths & Weaknesses

↑ Strengths

One-line neural network creationmedium

Simplified deep learning model building processmedium

Flexibility in defining various types of neural networksmedium

↓ Weaknesses

Limited flexibility for advanced customizationhigh

The one-line approach restricts users from fine-tuning network architectures beyond basic configurations.

Poor documentation and example coveragemedium

Official documentation lacks detailed examples and explanations for complex use cases, leading to a steep learning curve.

Small community and limited supporthigh

GitHub issues are infrequently addressed by maintainers, and the user base is relatively small compared to more established frameworks like TensorFlow or PyTorch.
