cbcbox

✓ import cbcbox

cbcbox is a module that provides the CBC binary path; no classes typically imported.

Verifies that the CBC binary shipped with cbcbox exists. Then use with PuLP or or-tools by specifying the solver path.

import cbcbox from pathlib import Path cbc_path = Path(cbcbox.__file__).parent / 'cbc' print('CBC executable found at:', cbc_path.exists())

cbc --version

Debug

Known issues

deprecatedSome OS-specific wheels are not updated; Linux x86_64 and macOS x86_64 are supported, but ARM macOS may see delays.

fix

Use the conda-forge version of CBC or compile from source if your platform lacks a wheel.

affects: <=2.929

gotchaThe binary may not have execute permissions after installation on some systems; you may need to chmod +x.

fix

Run: import subprocess; subprocess.run(['chmod', '+x', cbc_path])

affects: all

breakingVersion numbering changed between major releases; do not rely on version comparisons.

fix

Check for the existence of the binary rather than pinning a specific version.

affects: >=2.0

gotchacbcbox does not expose a Python API; it only bundles the binary. Use PuLP or or-tools to actually solve models.

fix

Install a modeling library like PuLP: `pip install pulp` and then set solver path to cbcbox's CBC binary.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'cbcbox'

Package not installed or installed in a different environment.

fix

Run `pip install cbcbox` in the correct Python environment.

FileNotFoundError: [Errno 2] No such file or directory: '.../cbc'

CBC binary missing due to incomplete installation or wrong platform.

fix

Ensure you are on a supported platform (Linux x86_64, macOS x86_64). For others, install CBC via conda or compile from source.

PermissionError: [Errno 13] Permission denied: '.../cbc'

Binary lacks execute permission on Linux/macOS.

fix

Run `import subprocess; subprocess.run(['chmod', '+x', str(cbc_path)])` after importing cbcbox.
