Description

aws-neuron/aws-neuron-sdk#1100

This use case worked in 2.20 SDK, but it does not in 2.21. Looks like, this kind of issue had occurred in previous versions. aws-neuron/aws-neuron-sdk#1023. I have raised an issue in aws neuron sdk regarding this. And tp_degree 1 is a valid use case. Till they fix it, we could add tp_degree = 2 in our test cases.

And also, will update this in our release notes in the known issues section.
