Hello p146103,

Thank you for posting on TensorRT Forum. In order for the community to effectively help you, please describe the issue you are seeing.

What is your platform/GPU? What is the usage scenario? What commands are you executing when you see the error? Any usage/source file you can provide will help us debug too.

I have Frozen graph file I want to convert Frozen graph to trt_graph(Tensorrt graph) to speed up my model.
I want to use this trt_graph for object detection Problem

code link:https://gist.github.com/qinyao-he/28ddedb7f561bb3cb4ba880833f14a89

Frozen Grpah file:https://drive.google.com/file/d/1VDbtLbZmmEgbQq-sY-A32NBhDV_xv8TE/view?usp=sharing

You can suggest me an other code for frozen_graph to tensor_rt grpah

Platform and pakages

Linux:16.04
Gpu:GTX 1080
TensorRt:4.0.1.6
Tensorflow:1.10
Python:3.5

Hello,

this seems to be TF specific issue.

def get_frozen_graph(graph_file):
  """Read Frozen Graph file from disk."""
  with tf.gfile.FastGFile(graph_file, "rb") as f:
    graph_def = tf.GraphDef()
[b]    graph_def.ParseFromString(f.read())
[/b]  return graph_def

Can you try TF 1.9 and see if this goes away?
