Only one AI Inference Server application instance can be installed on an edge device. If you try to install more than one application instance with different MLFB numbers, you’ll get error messages, and you won’t be able to use AI Inference Server.
If you would like to upgrade the AI Inference Server application from version 1.3.0 (or newer) to version 1.4.0 (or newer), please use the Industrial Edge Management System and perform the following steps:
Before you start the upgrade process, please make sure all running pipelines are stopped.
Press "Install" button on "AI Inference Server" app in the catalog of Edge Management.
Select each config file.
Click on the edit button of "config.json" file.
Please replace the content to the following text:
{
"embedderApi": "http://pipes_api:44444/v2",
"sharedVolume": "/ai-ml-manager-agent/deployments",
"statusUpdateInterval": "10s",
"sqliteDsn": "file:/ai-ml-manager-agent/database/agent.db?mode=rwc&journal_mode=WAL&_mutex=full&_synchronous=normal"
}Press "Update" button
Press "Next" button
After the upgrade process, you can continue the work with your AI Inference Server.
After the software upgrade, any tags which were selected on the user interface will not be available. You can easily add them back manually after the upgrade is complete.
