title: AttributeError: module 'sqlalchemy' has no attribute 'engine'
body: <p>I am using Pandas to get data from a Microsoft SQL Server.
  I use <code>read_sql_query</code> and I don't understand why I have the following error:</p>
  
  <pre><code>in read_sql_query
      pandas_sql = pandasSQL_builder(con)
  in pandasSQL_builder
      if _is_sqlalchemy_connectable(con):
  in _is_sqlalchemy_connectable
      return isinstance(con, sqlalchemy.engine.Connectable)
  </code></pre>
  
  <blockquote>
  <pre><code>AttributeError: module 'sqlalchemy' has no attribute 'engine'
  </code></pre>
  </blockquote>
  
  <p>I use Python 3.6
  My version of Pandas is 0.19.2
  My version of sqlalchemy is 1.1.15</p>
