Import: No module named manages.alert.views

Question

I am trying to use the following function defined in gerencia/alert/views.py

def maLogger(level, message, node=None):

    aux=0
    if level=='Critical_client':
    aux=2
    date = datetime.datetime.now()
    log = Log(level=level, date=date, node=node, message=message, flood=aux)
    log.save()

I’ve tried calling her from the archive mad_weka.py but gives error in import

[wilker@centos7 gerencia]$ python
Python 2.7.5 (default, Sep 15 2016, 22:37:39) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from mad_weka import Mad
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "mad_weka.py", line 7, in <module>
    from gerencia.alert.views import maLogger
ImportError: No module named gerencia.alert.views

Below follows the directory tree

[wilker@centos7 MeshAdmin]$ tree
    .

Although I put it in the directory /mad or in itself /alert, I get the same error. What I need to do for Python sees the file views.py?

Try this in your home directory:

$ mkdir teste1
$ cd teste1
$ mkdir gerencia
$ touch gerencia/__init__.py
$ mkdir gerencia/alert
$ touch gerencia/alert/__init__.py

The tree should look like this:

.
└── gerencia
    ├── alert
    │   ├── __init__.py
    │   └── views.py
    └── __init__.py

With a text editor create a file views.py in gerencia/alert. using the vim in the example below:

vim gerencia/alert/views.py

def hello():
    print ('Hello World!')

Now test import in python terminal:

$ python
>>> from gerencia.alert.views import hello
>>> hello()
Hello World!

Can’t be sure by the 'tree' you posted, probably missing __init.py__ in the business gerencia.

Edict
In the above example the call from gerencia.alert.views import hello takes into consideration that the python terminal was called from the "root" of the tree, if vc is in the same directory where the .py from which you want to import then the command must be difetent, for example:

$ cd gerencia\alert
$ python
>>> from views import hello
>>> hello()
Hello World!
