Hi
I have created a model which has a log softmax layer at the end, I have trained and converted the model to onnx format.
But while converting it to IR format using OpenVINO I'm getting error as below:
[ ERROR ]
[ ERROR ] It can happen due to bug in custom shape infer function <UNKNOWN>.
[ 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 ] There is no registered "infer" function for node "LogSoftmax_177" with op = "LogSoftmax". Please implement this function in the extensions.
For more information please refer to Model Optimizer FAQ (https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html), question #37.
Stopped shape/value propagation at "LogSoftmax_177" node.
For more information please refer to Model Optimizer FAQ (https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html), question #38.
Exception occurred during running replacer "REPLACEMENT_ID" (<class 'extensions.middle.PartialInfer.PartialInfer'>): There is no registered "infer" function for node "LogSoftmax_177" with op = "LogSoftmax". Please implement this function in the extensions.

Can anyone please tell me how to solve this issue!

Greetings,
First and foremost, before you try to convert, you need to ensure that the topology/models are supported by openvino. You can refer here: https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_convert_model_Convert_Model_From_ONNX.html
Once you are sure, you can refer to this video for detailed convertion progress: https://www.youtube.com/watch?v=cbdS3BjjbaQ
You can also refer to here if these models are relevant to yours:
- https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_convert_model_onnx_specific_Convert_Mask_RCNN.html
- https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_convert_model_onnx_specific_Convert_DLRM.html
