Hello, I wanted to run this test(https://devblogs.nvidia.com/tensorrt-integration-speeds-tensorflow-inference/) to test the TensorFlow-TensorRT integration.

I could normally run this test, but while I tried to modify the code fitting the facenet model(.pb) by davidsandberg, https://github.com/davidsandberg/facenet, I got some problem. ><

how to solve it or what is that mean? Thank u.

Tensorflow version: 1.7.0-rc1

CUDA/cuDNN version: 9.0 / 7.0.5

TensorRT version: 4.0.0.3

GPU model and memory: GTX 980M, 4Gb
