Does OpenVino include mvnc?

No.

SingleStickSSDwithRealSense.py -> for NCSDK
SingleStickSSDwithRealSense_OpenVINO_NCS2.py -> for OpenVINO
SingleStickSSDwithUSBCamera_OpenVINO_NCS2.py -> for OpenVINO

Thanks for reply.
Different error occurs as following:
Traceback (most recent call last):
File "SingleStickSSDwithRealSense_OpenVINO_NCS2.py", line 31, in
pipeline.start(config)
RuntimeError: Couldn't resolve requests

ps: Intel RealsenseD435 is attached and Realsense sdk 2.0 is installed.

Thanks PINTO039.
I still got some error messages. I try to obtain the supported models by enumerate_devices, it shows:

Some articles mentioned that Color modes only support in USB3.0. Raspberry Pi 3 only equips USB2.0. However, your demonstration seems is executed on Raspberry 3 Pi. So strange..
By the way, the version of FW is 5.11.

[PINTO0309]

Please see the following.
https://realsense.intel.com/intel-realsense-downloads/#firmware

I do not strongly recommend 5.11.
Use only "Production ready release".
"Development release" is always very unstable.

• Firmware 5.10.6
  https://downloadmirror.intel.com/28237/eng/Intel%C2%AE%20RealSense%E2%84%A2D400%20Series%20Signed%20Production%20Firmware%20v5_10_6.zip

• SDK 2.16.5

$ git clone -b v2.16.5 https://github.com/IntelRealSense/librealsense.git
$ cd ~/librealsense
$ git checkout -b v2.16.5
$ mkdir build;cd build
$ cmake .. -DBUILD_EXAMPLES=true -DCMAKE_BUILD_TYPE=Release
# For RaspberryPi3
$ make -j1
$ sudo make install

Really appreciate your kind response.
FW5.10.6 does not work for me. There is still no color mode when running rs-enumerate-devices. Only 5.10.3 contains color mode. Neither in 5.10.13 and other versions.
But depth mode was disappeared in 5.10.3. Therefore, I have to remark the related codes in SingleStickSSDwithRealSense_OpenVINO_NCS2.py.
However, both color and depth modes work in MultiStickSSDwithRealSense_OpenVINO_NCS2.py. I will try to discover the differences between these two programs.
