title: Pip install openslide completes successfully but when I import it "the specified module is not found"
body: <p>I need to open SVS images in Python 3.7 and it seems that Openslide is the only module capable of opening images of that size (30k*30k pixels). I have used <code>pip install openslide-python</code> as well as <code>python -m pip install openslide-python</code> and <code>pip 3 install...</code> etc.</p>
  
  <p>I know the module has been successfully installed because if I run any of those commands again the command line returns <code>requirement already satisfied</code> however when I run Python and try to <code>import openslide</code> it gives the error at the bottom.</p>
  
  <p>My guess was that the .whl or .tar.gz files were in the wrong path so I made a bunch of copies and put them in the openslide folders within the Anaconda3 folder. The error persists. I have included the full error code below for clarity.</p>
  
  <p><strong>Extra:</strong> If I run <code>help("modules")</code> openslide shows up along with numpy, math, sklearn etc. I can import and run all other modules without issue.</p>
