title: Why does mypy state "found module but no typehints..." eventhough there are actually type hints?
body: <p>I have a service that imports modules from a directory containing a lot of packages and modules. Most of the modules in that directory are annotated with type hints.<br></p>
  <p>Now, I want to check my type hints in the service with <code>mypy</code>. But for some reason, <code>mypy</code> doesn't recognize the hints in that directory and I get a lot of errors like:</p>
  <blockquote>
  <p>service/some.py:16: error: Skipping analyzing
  &quot;directory.some_package.some_arbitrary_module&quot;: found module but no
  type hints or library stubs</p>
  </blockquote>
  <p>I also already tried running <code>stubgen some_arbitrary_module.py</code> and putting the resulting <code>some_arbitrary_module.pyi</code> file in the same directory in order to check if there is something wrong with the type hints in the <code>some_arbitrary_module.py</code>.. but I get the same error.</p>
  <p>Is there something else that can cause this kind of error?</p>
