OpenVino Model Optimizer-Shape [-1 -1 -1 1] is not fully defined for output 0 of "image"

I am trying to help convert trained tensorflow model hfnet, I have no idea about more information about this model(I don't know the --input_shape parameter).this is the folder structure.

.
├── hfnet
│   ├── checkpoint
│   ├── config.yaml
│   ├── events.out.tfevents.1541966416.lo-s4-033
│   ├── log
│   ├── model.ckpt-83096.data-00000-of-00001
│   └── model.ckpt-83096.index
└── saved_models
    └── hfnet
        ├── saved_model.pb
        └── variables
            ├── variables.data-00000-of-00001
            └── variables.index

command:

python3 mo_tf.py --saved_model_dir /home/intel/hfnet/saved_models/hfnet/

I get the following error:

Hi Rachel,

You can analyze your model using summarize graph tool and that should be able to tell you information about your inputs and outputs. The python tool is in /opt/intel/openvino/deployment_tools/model_optimizer/mo/utils/. To understand how to run it type summarize_graph.py -h.

Also taking a look at the github and knowing Tensorflow extensively your input tensor is in the form of [Batch,Height,Width,Channels] with color channels being 1.

So if you know that you'll only be processing 1 image at a time and you know the height and width of the test images you can fill this in for example  if your image resolution is 300x300 then try 

python3 mo_tf.py --saved_model_dir /home/intel/hfnet/saved_models/hfnet/ --input_shape [1,300,300,1] 

Let me know if this helps.

Kind Regards,

Monique Jones

Hi Monique,

Thanks for sharing your idea. I got the same error as Rachel, but I'm trying to convert an onnx model. Looks like summarize_graph tool is only for TensorFlow model? Do you know is there any tool can get the input shape of an onnx model?

Thanks,

Daisy
