In research environments (e.g., containers), pip might face restricted system-wide access or broken distributions.

Handling Externally Managed Environments: If pip install fails with "externally-managed-environment", use --break-system-packages cautiously or create a virtual environment (python -m venv).
Fixing Broken Package Distributions:
- Symptoms: OSError: cannot open shared object file or WARNING: Ignoring invalid distribution ~orch.
- Solution: Uninstall the broken distribution and reinstall.
```
pip uninstall <pkg> -y --break-system-packages
pip install <pkg>==<version> --break-system-packages
```
Managing Missing Shared Objects: Always verify the installation of hardware-dependent libraries like torch or flash-attn by running a basic script to import them.

Use python -VV and pip freeze to ensure the runtime state is documented for reproducibility.
