does tensorflow 1.13.2 have problem?

[phoenixkillerli]

my test environment:

docker pull tensorflow/tensorflow:1.13.2-gpu-py3

and I found the lastest saved model

root@3ec62ce01961:~/StegaStamp# du -sm saved_models/7/*
208     saved_models/7/saved_model.pb
0       saved_models/7/variables

but the released model is

(tf1.13) [phoenixkiller@ultrapower stegastamp_pretrained]$ du -sm *
1	saved_model.pb
207	variables

Does I got pb model?
And I still could not get the performance same as release model.
Should I change tensorflow version to 1.13.1?
