@peterghaddad Thanks for the comments! So, for the error occuring in the new stack we need to dig into this deeper. I have a guess, where this is rooted. I come back to you when I know more.

@simonsays1980 Appreciate you diving in! From a quality and training perspective, I think this example is good to go. LSTM isn't necessary for us to move forward; however, i'm glad we are finding things that can be fixed!
