@dwullery Can you copy and paste the full traceback for the error? It's impossible that it is exactly the same error, since the OP's error explicitly mentions scipy in the error message.

Also, you should try force-restarting Pythonista. (Double-click the home button, swipe Pythonista away to the top, then start Pythonista again from the home screen.) Sometimes when you stop a script while it is importing a module, it can get stuck in a half-imported state that causes lots of errors. The best way to fix that is to fully restart the app.
