“ReplacementID” Error When Converting Open Neural Network Exchange (ONNX) Model to Intermediate Representation (IR) Format

Converted ONNX model to OpenVINO™ IR format using Model Optimizer command:

--input_model "{onnx_path}
--input_shape [1,512, 896, 3], [1,512, 896, 4]
--input frame, prob
--data_type FP16
--output_dir "{model_path.parent}"

Received error:

[ ERROR ] Exception occurred during running replacer "REPLACEMENT_ID" (<class 'extensions.front.user_data_repack.UserDataRepack'>): No node with name frame

The Model Optimizer did not recognize the input nodes frame and prob, due to wrongly specifying the input nodes of the model.

1. Check the correct input nodes for the model using Netron.
2. Change the input nodes option from --input frame, prob to --input 0,1.
