Import error, No module named xxxx [duplicate]

Question

I have a project having the structure

/example ../prediction ....__init__.py ....a.py 

PYTHONPATH is pointed to /example

now I open the python in terminal and type

import prediction 

it succeeded, but if I type

import prediction.a 

it returns error

ImportError: No module named 'prediction.a'; 'prediction' is not a package 

why is that? isn't that already imported as a package

Answer 1

The behavior you are seeing can be caused if there is a module (foo.py) or package (foo/__init__.py) in your current directory that has a conflicting name.

In your case, I suspect there is a file named prediction.py, and you're getting that instead of the prediction package in your examples directory.
