Answer 1

我对问题的评论显然解决了问题:

Python 3.5.2 and unixODBC 2.3.1 sounds like Ubuntu 16.04. Some packages in the Ubuntu repositories can be very old, e.g., unixODBC 2.3.1 is almost 7 years old now. Since it is unixODBC that is crashing (in SQLDriverConnectW) you might want to try upgrading it to the latest version (currently 2.3.7).
