AI Engine Configuration

• AI Engine failed to be started: Check whether the IP address and port are available and whether the CA certificate path exists.
• AI Engine does not respond: Check whether the CA certificates of the two communication parties are consistent.
• Training and test failure: Check whether the path for saving the model files exists and whether the training prediction file is correctly downloaded.
• Changing the AI Engine IP address: Regenerate the certificate by following the steps in Generating Certificates. Enter the new IP address in Generate a certificate and private key.
