Error parsing message

[MingshanHe]

I have run my own model but there are some wrong as this:
od_graph_def.ParseFromString(serialized_graph)
google.protobuf.message.DecodeError: Error parsing message

OS: Ubuntu 20.04
ROS: noetic
TF: 2.4.1
Python: 3.8.5

Help me Please.

That seems like an error coming from how this package and/or your configuration is using TensorFlow, because the ROS wrapper in this package does not use protobuf. If you follow the instructions in the README of this package using a pre-trained SSD model, does it work as expected?

Yes, It's exactly worked. But I would like to use my own training model which is used tensorflow, and it doesn't work like that. So it‘s any wrong in the protobuf?

Hi Mingshan, I am encountering the same issue. Did you ever find out how to add you own model. I followed TensorFlow object detection api to train and export my model. The file format are different and there is no .meta. file. I wonder how can I replace the example model with mine.

I am so sorry that my project is completed in Feb 2021. And I forgot the main steps to solve this issue. But I have the successful project repository which I think could be helpful for you.
