OpenVIVO Caffe model optimizer error

[Nair__Dinesh]

I recently installed OpenVIVO and the demo applications work well.

I get an error when trying to optimize the SSD_GoogleNetV2.caffemodel that is provided by Intel.

Steps followed:

1. Activate environment:

source /opt/intel/computer_vision_sdk_2018.1.249/deployment_tools/model_optimizer/install_prerequisites/../venv/bin/activate

2. Run model optimizer:

python3 mo.py --input_model ~/local/examples/intel_model/SSD_GoogleNetV2.caffemodel --input_proto ~/local/examples/intel_model/SSD_GoogleNetV2_Deploy.prototxt

The following error message is generated:

[ ERROR ]  -------------------------------------------------
[ ERROR ]  ----------------- INTERNAL ERROR ----------------
[ ERROR ]  Unexpected exception happened.
[ ERROR ]  Please contact Model Optimizer developers and forward the following information:

    exec("import {}".format(modules[name] if name in modules else name))
  File "<string>", line 1, in <module>
ImportError: No module named 'networkx'

[ ERROR ]  ---------------- END OF BUG REPORT --------------
[ ERROR ]  -------------------------------------------------

I've confirmed that networkx is installed.

Thanks,

Hi Nair Dinesh,

I'm not sure you did install prerequisites for caffemodel conversion but,

Can you try this?

1. Model optimizer prerequisites installation for caffe model

	$ sudo apt-get -y install python3-pip virtualenv cmake libpng12-dev libcairo2-dev libpango1.0-dev libglib2.0-dev libgtk2.0-dev libgstreamer0.10-dev libswscale-dev libavcodec-dev libavformat-dev python3-yaml
	$ cd /opt/intel/computer_vision_sdk/deployment_tools/model_optimizer/install_prerequisites
	$ sudo ./install_prerequisites.sh
	
	$ cd /opt/intel/computer_vision_sdk/deployment_tools/model_optimizer
	$ source /opt/intel/computer_vision_sdk/bin/setupvars.sh
	$ source ./venv/bin/activate

2. Model conversion

	// IR files, FP32 version, will be created in ~/Desktop/IR/FP32
	$ python3 ./mo.py --input_model ~/local/examples/intel_model/SSD_GoogleNetV2.caffemodel --output_dir ~/Desktop/IR
