Detailed description

I am trying to optimize a model I retrained using tensorflow's object detection API but am running into the issue below.

Model Optimizer arguments:
Common parameters:
- Path to the Input Model: /model/frozen_inference_graph.pb
- Path for generated IR: /.
- IR output name: frozen_inference_graph
- Log level: ERROR
- Batch: Not specified, inherited from the model
- Input layers: Not specified, inherited from the model
- Output layers: Not specified, inherited from the model
- Input shapes: Not specified, inherited from the model
- Mean values: Not specified
- Scale values: Not specified
- Scale factor: Not specified
- Precision of IR: FP16
- Enable fusing: True
- Enable grouped convolutions fusing: True
- Move mean values to preprocess section: False
- Reverse input channels: True
TensorFlow specific parameters:
- Input model in text protobuf format: False
- Path to model dump for TensorBoard: None
- List of shared libraries with TensorFlow custom layers implementation: None
- Update the configuration file with input/output node names: None
- Use configuration file used to generate the model with Object Detection API: /model/pipeline.config
- Operations to offload: None
- Patterns to offload: None
- Use the config file: /openvino/ssd_1.14.json
Model Optimizer version: unknown version
The Preprocessor block has been removed. Only nodes performing mean value subtraction and scaling (if applicable) are kept.

The above exception was the direct cause of the following exception:
