What is default resource (CPU/VPU) while running "python3 ./stream_infer.py" on Ubuntu 16.04LTS-X64?

When I run "$ python3 ./stream_infer.py" command, I have monitored strange situation.

While running ./stream_infer.py, I though that Movidius's VPU will be execute the request of

./stream_infer.py. However, CPU is running 100% cpu usage on CPU #1 for doing ./stream_info.py

Why does CPU spend CPU resource continually instead of Movidous's VPU? And, How can we monitor

the usage information of VPU(Vision Processing Unit)?

1.5.1 Verify the directory structure and contents

$ cd <ncapi directory>/tools
$ ./get_models.sh
$./convert_models.sh
$ cd <ncapi directory>/py_examples/stream_infer
$ python3 ./stream_infer.py
