python import problem
<p>although there are many posts on the internet as well as some posts on stack overflow, I still want to ask about this nasty python "import" problem.</p>

<p>OK. so, the open source code organization is usually like this:</p>

<p>project/src/model.py;</p>

<p>project/test/testmodel.py</p>

<p>if I put the famous <code>__init__.py</code> in project directory and also in src/ and test/ subdirectories, 
and then put "from project.src import model" for the testmodel.py. 
it does not work! keep telling me that the Module named "project.src" is not found!</p>

<p>how can I solve the problem without changing the code structure?</p>
