   Hi @twmht  , good day to you.
   
    I tried executing your script and I get the following error :
   
   > 
    **InternalError: Check failed: original_producers.size() == 1u (0 vs. 1) :**
   
   I traced the error to its source and it seems to be from the 
ToMixedPrecision() Pass. Has something to do with float16 handling by the 
metascheduler. Can you confirm if you have faced an error similar to this? Were 
you able to solve this? Or atleast find out the exact nature and source of this 
bug?
   
   Can you please let me know if you were able to find a workaround for this? 
TIA and have a nice day!
   
   Regards,
   
   Krishna
