**A:** This error occurs when an incorrect input port is specified with the ``--input`` command line argument. When using ``--input``, you may optionally specify an input port in the form: ``X:node_name``, where ``X`` is an integer index of the input port starting from 0 and ``node_name`` is the name of a node in the model. This error occurs when the specified input port ``X`` is not in the range 0..(n-1), where n is the number of input ports for the node.

**A:** This error occurs when an incorrect combination of the ``--input`` and ``--input_shape`` command line options is used. Using both ``--input`` and ``--input_shape`` is valid only if ``--input`` points to the ``Placeholder`` node, a node with one input port or ``--input`` has the form ``PORT:NODE``, where ``PORT`` is an integer port index of input for node ``NODE``.

The ``single_input_node`` function can be used only for ports that has a single consumer inside the matching sub-graph. When multiple nodes are connected to the port, use the ``input_nodes`` function or ``node_by_pattern`` function instead of ``single_input_node``.

#####################################################################################################################################################
|
||||
|

**A:** Model Optimizer cannot infer shapes or values for the specified node. It can happen because of the following reasons: a bug exists in the custom shape infer function, the node inputs have incorrect values/shapes, or the input shapes are incorrect.

#####################################################################################################################################################
|
||||
|
||||
**A:** Batch dimension is the first dimension in the shape and it should be equal to 1 or undefined. In your case, it is not either equal to 1 or undefined, which is why the ``-b`` shortcut produces undefined and unspecified behavior. To resolve the issue, specify full shapes for each input with the ``--input_shape`` option. Run Model Optimizer with the ``--help`` option to learn more about the notation for input shapes.

**A:** This error occurs when the ``--input`` command-line option is used to cut a model and ``--input_shape`` is not used to override shapes for a node, so a shape for the node cannot be inferred by Model Optimizer. You need to help Model Optimizer by specifying shapes with ``--input_shape`` for each node specified with the ``--input`` command-line option.

**A:** There are many flavors of Caffe framework, and most layers in them are implemented identically.
|
||||
However, there are exceptions. For example, the output value of layer Interp is calculated differently in Deeplab-Caffe and classic Caffe. Therefore, if your model contains layer Interp and the conversion of your model has failed, modify the ``interp_infer`` function in the ``extensions/ops/interp.op`` file according to the comments in the file.

**A:** It means that your mean/scale values have a wrong format. Specify mean/scale values in the form of ``layer_name(val1,val2,val3)``.
|

You need to specify values for each input of the model. For more information, refer to the :doc:`Converting a Model to Intermediate Representation <openvino_docs_MO_DG_prepare_model_convert_model_Converting_Model>` guide.

**A:** It means that you are trying to convert a topology contains the ``_contrib_box_nms`` operation which is not supported directly. However, the sub-graph of operations including ``_contrib_box_nms`` could be replaced with the DetectionOutput layer if your topology is one of the ``gluoncv`` topologies. Specify the ``--enable_ssd_gluoncv`` command-line parameter for Model Optimizer to enable this transformation.

#####################################################################################################################################################
|

|
||||
**A:** If a ``*.caffemodel`` file exists and is correct, the error occurred possibly because of the use of Python protobuf implementation. In some cases, error messages may appear during model parsing, for example: "``utf-8`` codec can't decode byte 0xe0 in position 4: invalid continuation byte in field: mo_caffe.SpatialTransformerParameter.transform_type". You can either use Python 3.7 or build the ``cpp`` implementation of ``protobuf`` yourself for your version of Python. For the complete instructions about building ``protobuf`` from sources, see the appropriate section in the :doc:`Converting Models with Model Optimizer <openvino_docs_MO_DG_Deep_Learning_Model_Optimizer_DevGuide>` guide.

Q100. What does the message "SyntaxError: 'yield' inside list comprehension" during MxNet model conversion mean?
|

#####################################################################################################################################################
|
||||
|
||||
**A:** The issue "SyntaxError: ``yield`` inside list comprehension" might occur during converting MXNet models (``mobilefacedet-v1-mxnet``, ``brain-tumor-segmentation-0001``) on Windows platform with Python 3.8 environment. This issue is caused by the API changes for ``yield expression`` in Python 3.8.
|
||||
The following workarounds are suggested to resolve this issue:
|
||||
1. Use Python 3.7 to convert MXNet models on Windows
|
||||
2. Update Apache MXNet by using ``pip install mxnet==1.7.0.post2``
|
||||
Note that it might have conflicts with previously installed PyPI dependencies.
