Thanks @patrickvonplaten 

Thanks for adding this! I will let Suraj review the Flax code, as I'm not that familiar with it.

Thanks for the review @patil-suraj 
done changes according to review


@kamalkraj - could you merge master into this PR or rebase to master ? :-) Think this should solve the pipeline failures

@patrickvonplaten done
