  Software developers are increasingly using machine learning APIs to implement
'intelligent' features. Studies show that incorporating machine learning into
an application increases technical debt, creates data dependencies, and
introduces uncertainty due to non-deterministic behaviour. However, we know
very little about the emotional state of software developers who deal with such
issues. In this paper, we do a landscape analysis of emotion found in 1,245
Stack Overflow posts about computer vision APIs. We investigate the application
of an existing emotion classifier EmoTxt and manually verify our results. We
found that the emotion profile varies for different question categories.
