Import error: cannot import name 'label_cython' - ubuntu-16.04

Question

I am a new user for Ubuntu16.04 as well as caffe.
Few days ago I was working with Intel Movidius with the ncappzoo thingy and it worked. Afterward I tried to download the toolkit and API to play with. As I was verifying the installation of the toolkit, I found that the function importing caffe can no longer work. It keeps giving me this error.
I tried googling but find no solution. The $PYTHONPATH was check and verified. I also reinstalled the scikit-image.
Here's the block of gibberish thingy it bounced back to me :

File "/usr/local/lib/python3.5/dist-packages/skimage/measure/_label.py", line 1, in <module>
from ._ccomp import label_cython as clabel
ImportError: cannot import name 'label_cython'
Any idea what went wrong?

We are able to make use of all the apps/networks available from ncappzoo without any issues.
Our configuration is as follows:
movidius#osboxes:~$ python --version
Python 2.7.12
movidius#osboxes:~$ echo $PYTHONPATH
:/opt/movidius/caffe/python
movidius#osboxes:~$ lscpu | grep "Model name"
Model name: Intel(R) Core(TM) i5-5300U CPU # 2.30GHz
movidius#osboxes:~$ lsb_release -a
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial
Assuming that you have downloaded the ncsdk and then installed it. If not,
First we need to install 'ncsdk' which enable rapid prototyping, validation, and deployment of deep neural networks
please follow the links mentioned below to install ncsdk
(It includes software tools, API and examples)
https://developer.movidius.com/start
https://movidius.github.io/ncsdk/install.html
once the ncsdk installation is suceessfull, then you can make use of all the apps/networks available in ncappzoo.
