Probably the error is that you're not posting the same code as you're 
executing.  The error message refers to a line:
     from mod import module

which is wrong in two ways.  But in your source, you show
    import mod.module1

which I expect should work.  (I didn't try it)

So run the source you posted, and if it still fails, show us the 
traceback from that same code.  Then somebody will spot the problem.
