Model crashes with dynamic shape after loading network

NewMember

I converted an onnx squeezenet model to IR using

 

 

python3 mo_onnx.py --input_model SSD_nms.onnx --input inputs,top_k_per_class,nms_iou,nms_score --input_shape [1,3,224,224],[1],[1],[1]

 

 

This step worked fine, but when I try to load the network it gives me the following error.

 

 

ie = IECore() 
net = ie.read_network(model=model_path, weights=weights_path)
print (net.layers)

File "ie_api.pyx", line 1170, in openvino.inference_engine.ie_api.IENetwork.layers.__get__ ValueError: get_shape was called on a descriptor::Tensor with dynamic shape

 

 

IR definition of the troublesome layer:

 

 

<layer id="351" name="selected_indices" type="NonMaxSuppression" version="opset1">
    <data box_encoding="center" sort_result_descending="0"/>
    <input>
        <port id="0">
            <dim>1</dim>
            <dim>10000</dim>
            <dim>4</dim>
        </port>
        <port id="1">
            <dim>1</dim>
            <dim>2</dim>
            <dim>10000</dim>
        </port>
        <port id="2"/>
        <port id="3"/>
        <port id="4"/>
    </input>
    <output>
        <port id="5" precision="I64">
            <dim>10000</dim>
            <dim>3</dim>
        </port>
    </output>
</layer>

 

 

Any help would be much appreciated.

Hi Aravind,


Inference Engine supports NonMaxSuppression layer by CPU plugin (via Extensibility mechanism) and also by Shape Inference feature.


More information is available at the following pages:
