AWS Personalize - Not able to set bptt and hidden dimensions explicitly through GUI

Question

Hi,
I am trying to train an Amazon Personalize Item recommendation solution using User Personalization recipe. I am trying to set the BPTT value explicitly to 6 and hidden dimension to 133. When I say create solution, these parameters are getting reset to 32 and 149. If I make the perfrom HPO as TRUE, these values are not defaulting to 32 and 149,  different value is  getting suggested.

Answer

Thanks for reporting the issue. Service team is aware of this issue and currently working on a fix.
As of now, the tentative date for deploying the fix is by the end of this month (02/28/2022).
In the meantime, you can still use APIs to create solution with hyperparameters you want to set.
