Hi

Heat templates are stevedore plugins. you have
"AWSTemplateFormatVersion.2010-09-09" that was installed (with pip install)
that needs 'sqlalchemy-migrate==0.9.1', but your system has
'sqlalchemy-migrate 0.9.6' (so it refuses to run)

I'd suggest reinstalling heat either with a proper package manager or "pip
install".
