Please try setting the Qt API to version 2 by doing the following in Spyder:
Tools..Preferences..Console..External Modules
Set the "API selection for QString and QVariant objects" pull down to "API
#2"
Close the dialog with OK.
After making this setting change, open a new Python console and try
importing mlab.
