## Details
<!-- Description of your issue -->
I tried to reproduce, but the final result was 35.6 (vs paper 18.3), I carefully checked and found that the matrix multiplication result of TF2.x and TF1.12 (paper use) have some differences, about 0.0001, and then Many layers of linear transformation and multiplication, the difference in output characterization of the last layer has reached about 0.1, which is enough to affect the results, and if the mem_len and tgt_len values in the experiment are swapped, ppl actually drops to 19.5, I can ensure that all loaded The parameters are correct, the code is completely referenced to the author's source code and changed to 2.0 version, so I want to ask if anyone has reproduced it with TF2.0
