Upload fail: Module 'tensorflow._api.v1.io' has no attribute 'gfile'

Hi,
We had successful uploads and evaluation recently, but since our last update, we had this error which resulted in upload failure:

We try to reset our repo to the last successful upload model and codes, but the error remain.
We try to fix this error according to https://github.com/google/gin-config/issues/9 by changing gin-config version to 0.1.4, this error remains still.

Anyone has idea how to fix this ?

We tried a few settings in setup.py, our last attempt success in uploading in debug mode using tensorflow-gpu==1.14

Not sure why since we trained in tensorflow-gpu==1.12
