Troubleshooting

Enabling logging

Qubo Solver uses the standard Python logging (external) module, under the "qubosolver" logger. By default, it stays silent — you need to configure logging yourself to see its output:

import logging

logging.basicConfig()
logging.getLogger("qubosolver").setLevel(logging.DEBUG)

WARNING (external) messages are actionable: they flag something you can likely fix yourself, such as an unusual or inconsistent input. INFO (external) and DEBUG (external) messages are lower-level diagnostic detail — they are less useful on their own, but can help when reporting an issue to support.
