Having some problem when optimize a gru model

[5xx]

Hi, I have some problems when optimize a model. The log shows is as follows: Exception occurred during running replacer "REPLACEMENT_ID" (<class 'extensions.middle.RNNSequenceNormalizeToIE.RNNSequenceNormalize'>): Something bad has happened with graph! Data node "gru_1" has 0 producers.

My version is2021.2.185

Here is my environment :

pyyaml
tornado==5.1.1
python-interface
python-consul
oss2
requests
numpy
gensim
keras==2.2.4
pandas
tensorflow==1.12.0

onnx==1.8.1

keras2onnx==1.7.0

Hi,

Could you provide which model and also demo application that you are using for further investigation?

Plus, your model's topology and framework layer.

Sincerely,

My openVINO version is 2021.2.185 .I have already provided my model struct but the model file cannot provide. I didn't run the demo because the error happened when model optimizing.

Since you can't share it, I would like to confirm whether your current model is using dynamic shape for the input?

If you are, the dynamic shape for RNN/GRU for ONNX model is yet to be supported. However, our developers have worked on this in Feb 2021 and possible implementation on the next version release of OV - ONNX RNN/GRU enable dynamic input shape by mitruska · Pull Request #4241 · openvinotoolkit/openvino (github.com)

Plus, I would like to clarify your model's topology and framework layer to ensure they are supported.

Sincerely,

Yes, the model is using dynamic shape.

Hope you are noted regarding the dynamic shape for RNN/GRU for ONNX model is yet to be supported,

as I mentioned in the previous reply.

Greetings,

Intel will no longer monitor this thread since we have provided a solution. If you need any additional information from Intel, please submit a new question.
