Python Error: ImportError: No module named engine

I'm trying to import matlab.engine module in a .py file that's going to be executed inside Matlab. Here is the process and files:

My test.py file:

# test.py
import matlab.engine

On Matlab, I do:

>> mod = py.importlib.import_module('test');
>> py.reload(mod)

Error msg:

Error using test><module> (line 1)

Python Error: ImportError: No module named engine

In my python file, even inside Matlab, when I just import matlab module, it works, but when I try to import engine, it fails...

How can I import matlab.engine module inside Matlab?

Obs.:

Module matlab imported inside Matlab:

 >> py.importlib.import_module('matlab')
ans = 
  Python module with properties:
    Buffer: [1×1 py.type]
    <module 'libmwbuffer' from 'C:\MATLAB\R2018b\bin\win64\libmwbuffer.pyd'>

Module matlab imported outside Matlab (cmd.exe, for instance):

>>> import matlab
>>> matlab
<module 'matlab' from 'C:\Python27\lib\site-packages\matlab\__init__.pyc'>

Is it a conflict?

The import matlab.engine works outside matlab, if I run in the cmd.exe, for example, it works.

Using Matlab 2018b, Python 2.7. Everything x64. Windows 7.

I have solved the issue.The issue caused by a script named 'matlab.py' in the folder which the script runs in.It's my mistake,i take half of day for it.

I had the same issue with Matlab 2018b, but the issue has been solved in a later version (currently using 2020b).

Can anyone from Mathworks expain what's changed?
