Getting “failed to import metagraph” when running the TRT saved_model converter workflow for TF 1.15

[liutao053877]

I have trained a NER model with tensorflow1.15 and save the model in pb file . when I want to convert it to a new pb with tensorRT.

Error log occured: tensorflow.python.framework.errors_impl.InvalidArgumentError: Failed to import metagraph, check error log for more info.

same problem as : https://forums.developer.nvidia.com/t/getting-failed-to-import-metagraph-when-running-the-trt-saved-model-converter-workflow-for-tf-1-15/157319

how can I fix it ? thank you

Looks like a TF bug or a tf2onnx bug?

you should check the pb model use saved_model_cli show ，see if it has default signature
