[KL730] BIE Conversion Crash (Err: 134) in AddDummyBnForSplitNode - LIAGCN Model

Nimesh · May 15

I am currently converting a skeleton-based action recognition model (LIAGCN) for the KL730. While the initial optimization stages complete successfully, the process fails during the BIE conversion with a hard assertion error in the compiler.

Error Stack Trace:
