✗ from bec_lib import BECMessage

Connect to a BEC Redis server and check aliveness. Requires a running Redis instance.

import os from bec_lib.client import AlazarClient client = AlazarClient( redis_host=os.environ.get('REDIS_HOST', 'localhost'), redis_port=int(os.environ.get('REDIS_PORT', '6379')), ) print(client.is_alive())

Debug

Known issues

breakingv3.0 removed the old 'bec_lib.alazar' module; use 'bec_lib.client.AlazarClient'.

fix

Replace 'from bec_lib.alazar import AlazarClient' with 'from bec_lib.client import AlazarClient'.

affects: >=3.0.0

deprecatedRedisConnector is deprecated in favor of direct client usage (AlazarClient).

fix

Use AlazarClient which internally manages the connector.

affects: <=3.130.3

gotchaThe package is installed as 'bec-lib' with a hyphen, but Python imports use 'bec_lib' with an underscore.

fix

Always use 'import bec_lib' in code, not 'bec-lib'.

affects: all

gotchaBy default, the client expects a Redis server on localhost:6379. If not running, connection will hang.

fix

Ensure Redis is running or provide different host/port via environment variables.

affects: all
