Connection refused

[JessicaGao8]

Hi, I encountered a problem: (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x14bf5ba319d0>: Failed to establish a new connection: [Errno 111] Connection refused')). The specific error information is as follows.

I'm not sure what the exact cause of the problem is, as it usually happens during the first or second experiment. However, the subsequent experiments proceed normally, providing evaluation results and final predictions after hyperparameter tuning. Occasionally, the connection refused.
