2. Solutions:
Find the Squeezenet1.1.caffemodel file

cd /home/kang/openvino_models/models/public/squeezenet1.1/
ls

Switch to the model_optimizer directory and use mo_caffe.py to optimize your models

cd /opt/intel/openvino/deployment_tools/model_optimizer
sudo ./mo_caffe.py  --input_model /home/kang/openvino_models/models/public/squeezenet1.1/squeezenet1.1.caffemodel --output_dir  ~/Downloads/

The parsed XML and bin are ready to use
