Configuring automatic training

Question

I am using the recent User-Personalization-v2  and set automatic training,  was not allowed to select automatic campaign selection of the latest training version and also i am not able to delete the old training versions that are no longer in use

So my questions are:

1.    How can i set my campaign to automatically pick latest version of training, i currently have to manually update campaigns
2.    Are we not allowed to delete unused training versions (i.e used and no longer latest)
3.   Will charges be incured on training version i am not able to delete that is unused

Accepted Answer

Not sure if this will help anyone with similar issue, so Solutions trainings are charged , and further charges are only when the solution version is called to recommend, meaning when it is attached to a campaign and used to recommend

So for versions created, no further charges asides the training charges, except its being used

Answer

1. This is a bug in the console and will be fixed. In the meantime, you can use the [UpdateCampaign](https://docs.aws.amazon.com/personalize/latest/dg/API_UpdateCampaign.html) API to update the campaign to auto-sync with the latest solution version. See sample [here](https://docs.aws.amazon.com/personalize/latest/dg/campaigns.html#create-campaign-sdk). Bear in mind that `itemExplorationConfig` is not supported for the User-Personalization-v2 recipe so leave it out of your UpdateCampaign API call.
2. Individual solution versions currently cannot be deleted. The only way to delete them is to delete the solution which deletes all solution versions for the solution.
3. You are only charged when solution versions are created.
