i pray for your success in finding the solution

[DzakirinMD]

i've noticed that your tf version is tensorflow==2.0.0b1. please note that as of TF 2.0 the contrib is not available anymore.

current workaround for me is to install older version of TF. for me TF 1.15.0 works the best for now.

reference: tensorflow/community#18 , tensorflow/models#7036

TF 2.0 is the latest official version now, yet tensor2tensor seems to not support it!
