ValueError: You passed in an iterable attribute but I cannot figure out its applicable type

问题

I am trying to convert facenet model(20170512-110547.pb) to onnx format using tf2onnx tool. But When I am trying to convert it using this command

python3 -m tf2onnx.convert\
    --input 20170512-110547.pb\
    --inputs input:0,phase_train:0\
    --outputs embeddings:0\
    --output model.onnx\
    --verbose

It is giving me this error

ValueError: ValueError: You passed in an iterable attribute but I cannot figure out its applicable type.

All I have is .pb file and tf2onnx tool.

I would be really grateful if someone could give time to answer this ! Thank you.

回答1:

I didn't remove phase_train input branch, and that was the root of this error, I created inference-only graph (referred-link), then it didn't give me any error.
