What is PCART?

PCART is an automated tool designed to detect and repair Python API parameter compatibility issues across library version upgrades.

Features

  • Fully Automated: End-to-end automation from API extraction to repair validation
  • Comprehensive Detection: Detects 5 types of API compatibility issues
  • Multi-Platform: Supports Linux and Windows
  • Multi-Library: Works with PyTorch, NumPy, SciPy, Pillow, scikit-learn, and more
