Training Failed error when training a similarity model in Predictive Intelligence

[boyan_kushlev]

I have a simple developer instance I requested from ServiceNow Developers a month ago. I want to use Predictive Intelligence to train a model on the existing knowledgebase articles in the database so that I can show related articles based on the current article's content. I installed the Predictive Intelligence plugin along with its dependencies.

When I go to Predictive Intelligence > Similarity > Solution Definitions and click on the Knowledge Similar Articles definition, I can see there are 1200 matching records from the kb_knowledge table. Fields are set to Short Description, Article Body, Wiki, and test fields - to Short Description. These are the default values. When I click on Update & Retrain at the bottom I can a training is scheduled in the Training Request Schedules tab. When I click on it and then click on Execute Now, and then go to the ML Solutions tab, I can see the state of the solution is showing "Configuration OR Network Error" (see attachment). I can keep retraining it, changing values, etc, etc, and all I get is this error. Once I retrain it, the previous solution would go to either "Training request timed out" or "Training is canceled".

I have no idea what is causing this issue. I found other people having a similar issue, but no resolutions whatsoever. Some respondents mentioned Predictive Intelligence doesn't work on personal developer instances, but this doesn't make a lot of sense - why is it on the plugin store in the first place? And if that's actually the case, what can I do to use it? Should I request a different type of instance? The documentation doesn't say anything about that.

Hello @Lener Pacania1 

I want to enable Knowledge Demand Insights on my instance and already installed com.snc.knowledge_ml plugin.

The similarity definition, i.e. Similar Knowledge Articles for HR Task, is read-only and there is no train option.

Can you please help me with some extra solutions since my PDI is not read-only.

Thanks & Regards

Unless there is an example table provided by ServiceNow I could use.
