Hi, I built the model in TF-serving-gpu, copied it to the server, and it starts fine.

When calling I get an error however:

I also found a discussion on that error here: https://stackoverflow.com/questions/45139423/tensorflow-error-failedpeconditionerror-attempting-to-use-uninitialized-variab

[ps-account]

( It could be related that I'm building this in TF-serving-gpu 1.9.0 )

[ps-account]

it probably is tensorflow/serving#594

will try again later either moving your example to 1.9.0 or moving my tf-serving-gpu to 1.8

[ps-account]

Hmmm, I did a pip install tensorflow-gpu==1.9.0 and run tf-serving-gpu 1.9.0 but I got the same error
