Model Optimizer Error

[Rushikesh_P_Intel]

Hi,

• using customer pre trained model I am facing error while I convert the model. Please find the attached error message. Please review and  help to resolve this error.

/opt/intel/computer_vision_sdk_2018.5.455/deployment_tools/model_optimizer/mo/ops/slice.py:111: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.

  value = value[slice_idx]

[ ERROR ]  Shape is not defined for output 0 of "Postprocessor/BatchMultiClassNonMaxSuppression/map/while/Slice_1".

[ ERROR ]  Cannot infer shapes or values for node "Postprocessor/BatchMultiClassNonMaxSuppression/map/while/Slice_1".

[ ERROR ]  Not all output shapes were inferred or fully defined for node "Postprocessor/BatchMultiClassNonMaxSuppression/map/while/Slice_1".

 For more information please refer to Model Optimizer FAQ (<INSTALL_DIR>/deployment_tools/documentation/docs/MO_FAQ.html), question #40.

[ ERROR ] 

[ ERROR ]  It can happen due to bug in custom shape infer function <function Slice.infer at 0x7f20449d92f0>.

[ ERROR ]  Or because the node inputs have incorrect values/shapes.

[ ERROR ]  Or because input shapes are incorrect (embedded to the model or passed via --input_shape).

[ ERROR ]  Run Model Optimizer with --log_level=DEBUG for more information.

[ ERROR ]  Stopped shape/value propagation at "Postprocessor/BatchMultiClassNonMaxSuppression/map/while/Slice_1" node.

Dear Purohit, Rushikesh S,

Did you ever resolve this ? I would like to help you with this issue but I don't have access to Dropbox. If you wish to transfer huge files (such as models) to me you can do so via Syncplicity - that is the easiest way.

You say that the model is "pre-trained". I assume this to mean that the customer did not custom train it. Is this the case ? Is it one of these models listed model optimizer supported tensorflow list ?

Thanks and I'm sorry it took so long to address this,

Shubha
