there is no checkpoint argument in the estimator.Estimator predict function

[ldscr]

Describe the Issue

i installed the tensorflow 1.1.0 on my RaspberryPi 2 successfully.
and run a python code which i have tested on a Ubuntu system.
the code used the tensorflow estimator to build a network.
when i run the code, i got this error:
ERROR: predict() got an unexpected keyword argument checkpoint_path
so i checked the estimator.py, found that the predict() do have no checkpoint_path argument,
so i added the checkpoint_path=None, solved the problem.

but i checked the code from tensorflow, the predict() do have argument checkpoint_path.
i think maybe i should share this here.
