scitex 2.7.3

A comprehensive Python library for scientific computing and data analysis

SciTeX

A Python framework for scientific research that makes the entire research pipeline more standardized, structured, and reproducible by automating repetitive processes.

Part of the fully open-source SciTeX project: https://scitex.ai

### What You Get With `@stx.session`

Both implementations produce **identical outputs**, but SciTeX eliminates 131 lines of boilerplate:
```bash
demo_session_plt_io_out/
├── demo.csv              # Auto-extracted plot data
├── demo.jpg              # With embedded metadata
└── FINISHED_SUCCESS/
    └── 2025Y-11M-18D-09h12m03s_HmH5-main/
        ├── CONFIGS/
        │   ├── CONFIG.pkl    # Python object
        │   └── CONFIG.yaml   # Human-readable
        └── logs/
            ├── stderr.log
            └── stdout.log

What SciTeX Automates:

• ✅ Session ID generation and tracking
• ✅ Output directory management (RUNNING/ → FINISHED_SUCCESS/)
• ✅ Argument parsing with auto-generated help
• ✅ Logging to files and console
• ✅ Config serialization (YAML + pickle)
• ✅ CSV export from matplotlib plots
• ✅ Metadata embedding in images
• ✅ Symlink management for centralized outputs
• ✅ Error handling and directory cleanup
• ✅ Global variable injection (CONFIG, plt, COLORS, logger, rng_manager)

Research Benefits:

• 📊 Figures + data always together - CSV auto-exported from every plot
• 🔄 Perfect reproducibility - Every run tracked with unique session ID
• 🌍 Universal format - CSV data readable anywhere
• 📝 Zero manual work - Metadata embedded automatically
• 🎯 3.3× less code - Focus on research, not infrastructure
