Version incompatibility issues are prevalent when reusing or reproducing deep
learning (DL) models and applications. Compared with official API
documentation, which is often incomplete or out-of-date, Stack Overflow (SO)
discussions possess a wealth of version knowledge that has not been explored by
previous approaches. To bridge this gap, we present Decide, a web-based
visualization of a knowledge graph that contains 2,376 version knowledge
extracted from SO discussions. As an interactive tool, Decide allows users to
easily check whether two libraries are compatible and explore compatibility
knowledge of certain DL stack components with or without the version specified.
A video demonstrating the usage of Decide is available at
