Python can't import package

Question

I have a package structure like:

thePackage/
 __init__.py
 moduleA.py
 moduleB.py
 moduleC.py

The __init__.py file contains

from . import moduleA

For simplicity I cd into the directory containing the foler thePackage.

When I try to import thePackage I get the error:

Traceback (most recent call last):
 File "<ipython-input-10-5fe9a18b3124>", line 1, in <module>
import thePackage
 File "C:\thePackage\__init__.py", line 2, in <module>
from . import moduleA
ImportError: cannot import name 'moduleA'

I've read a few posts like Importing packages in Python, but still can't figure out my problem. The accepted answer in that post suggests I should be able to import the submodule moduleA by import thePackage.moduleA, but when I try this I get the exact same error.

How can I important the package thePackage?

Also, how can I just import moduleA?

Answer 1

from thePackage import moduleA

• user3731622: Your answer is correct for how to import the module of a package. However, I had encountered a situation in which this method was failing.

Answer 2

I encountered the issue while using Spyder and Python3.4.

When I closed and restarted Spyder, I was able to import the package using import thePackage, and I was able to import moduleA using import thePackage.moduleA.

Also, originally when I first tried to import the module using import thePackage, it failed. At this point I might have modified and saved the __init__.py. Then I probably tried to import the module again using import thePackage, but maybe this doesn't always try to import the newly saved versions of thePackage. Thus, I recommend trying

import importlib
importlib.reload(thePackage)

to force the import of the newly saved version of thePackage.

Answer 3

you could try

 sudo apt-get install python-setuptools

found it at https://bitbucket.org/pypa/setuptools/issues/368/module-object-has-no-attribute-packaging, and it helped me when I was having challenges installing pyttsx,
