Hi,
I could not seem to import matlab.engine in python in my Ubuntu 15 as shown in the following figure:
The MATLAB Engine API for Python has been successfully installed following the instructions here http://au.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html
Does anyone have a solution for this issue?

This installation command, other than the original one, has worked for me: python setup.py build --build-base=$(mktemp -d) install

Anaconda may not work as MATLAB Engine API for Python supports CPython only:
http://www.mathworks.com/help/matlab/matlab-engine-for-python.html
Another issue to consider is whether your Python version support wide-Unicode:
http://www.mathworks.com/help/matlab/matlab_external/system-requirements-for-matlab-engine-for-python.html#buijf0m
Following code can be used to check it supports wide Unicode or not:
>>> import sys
>>> if sys.maxunicode > 65535:
... print 'wide-unicde'
... else:
... print 'narrow-unicode'

I had the same issue with mine. I am running Ubuntu 16.04 and Python 3.6 on Pycharm, and Matlab 2018a. After installing Matlab Python API as given on http://au.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html
it creates a folder structures like:
<installation-dir>/matlab/engine/
and
<installation-dir>/lib/ and <installation-dir>/lib.linux-x86-64-2.7/
or something like that. After I copied these directories into my Python project root they started working and I was able to import matlab.engine(). In Pycharm you can add source folders paths to your project; you can try something similar.

Nice. I have known the Python project root. Then, the folder structures like
installation-dir/matlab/engine/
should be coped into the Floder1. However, the Floder1 is not a writable file. Therefore, I do not know where the folder structures should be written into. I am just a Python beginner. It is appreciate for your help.

I have addressed my problem. I found that the Python could not find the Matlab module because my computer had two Python versions. Therefore, I pointed out the Python version when the API was installed, i.e. the installing code was changed as
python3 setup.py install
Best regards and thanks again.

I had same issue. I was trying it on Spyder but it didn't work. I rhen shifted to Pycharm and the error was gone. I guess there is some issue with Anaconda-Spyder.
