Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Limited support for non-English languages
Most examples and pre-trained models are in English, lacking comprehensive support for other languages
- 02
Resource-intensive operations can be slow on large datasets
Adversarial attacks and data augmentation processes may require significant computational resources and time
What it does well
Supports adversarial attacks to test model robustness
Facilitates data augmentation for training more resilient models
Provides tools for NLP model training and evaluation
