Based on the error it seems that the reshape operation in your model doesn’t satisfy following condition:
“-1 specifies that the dimension should be automatically deduced - this can only be used at most once in any given shape.”
Please refer below link for more details:

Thanks

Is that wrong with the training or wrong when I make an frozen inference graph?

What should I do to fix that error?

Hi,

Can you share the model and script file so that we can help better?

Thanks

I use ssd_mobilenet_v2 model.

research/object_detection/legacy/train.py : [models/train.py at master · tensorflow/models · GitHub

research/object_detection/export_inference_graph.py : https://github.com/tensorflow/models/blob/master/research/object_detection/export_inference_graph.py

6

Can you share the “frozen_inference_graph.pb” model file that you are using to TRT conversion?

Thanks

7

Do I have to upload the file here? I don’t know what ‘share frozen_inference_graph.pb’ means.

Yes, could you please share your model file?

Thanks
